A “prepper” is part of a community of people who are getting themselves ready to survive a large-scale disaster. For some this means a devastating hurricane, earthquake or other natural disaster. For others that disaster may involve the after effects of an EMP attack on American soil, or some other breakdown in society that leaves us all to fend for ourselves.
To be watchful applies to awareness of your own spiritual or moral condition.
Preppers often assemble a small personal arsenal, non-perishable food, medical supplies, and other survival gear. They sometimes take part in ongoing training in the skills needed to survive without heat, electricity or running water.
Some people call a prepper paranoid, and some wonder if they are simply wiser than the rest of us.
What are you afraid of?
Doomsday scenarios and ominous visions of the future are popular in many Hollywood productions. Societies and nations across the earth are in a growing state of turmoil and change. Traditional patterns of life and family are being replaced with new and strange alternatives. Some embrace the direction in which we are headed, while others worry.
Is there is a biblical reason to be concerned?
Did you know Jesus Christ, the Son of God, was also a prophet? The most extensive session of prophetic teaching from Jesus is found in Matthew 24:1-51 Matthew 24:1-51  And Jesus went out, and departed from the temple: and his disciples came to him for to show him the buildings of the temple.
 And Jesus said to them, See you not all these things? truly I say to you, There shall not be left here one stone on another, that shall not be thrown down.
 And as he sat on the mount of Olives, the disciples came to him privately, saying, Tell us, when shall these things be? and what shall be the sign of your coming, and of the end of the world?
 And Jesus answered and said to them, Take heed that no man deceive you.
 For many shall come in my name, saying, I am Christ; and shall deceive many.
 And you shall hear of wars and rumors of wars: see that you be not troubled: for all these things must come to pass, but the end is not yet.
 For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places.
 All these are the beginning of sorrows.
 Then shall they deliver you up to be afflicted, and shall kill you: and you shall be hated of all nations for my name's sake.
 And then shall many be offended, and shall betray one another, and shall hate one another.
 And many false prophets shall rise, and shall deceive many.
 And because iniquity shall abound, the love of many shall wax cold.
 But he that shall endure to the end, the same shall be saved.
 And this gospel of the kingdom shall be preached in all the world for a witness to all nations; and then shall the end come.
 When you therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoever reads, let him understand:)
 Then let them which be in Judaea flee into the mountains:
 Let him which is on the housetop not come down to take any thing out of his house:
 Neither let him which is in the field return back to take his clothes.
 And woe to them that are with child, and to them that give suck in those days!
 But pray you that your flight be not in the winter, neither on the sabbath day:
 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
 Then if any man shall say to you, See, here is Christ, or there; believe it not.
 For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so that, if it were possible, they shall deceive the very elect.
 Behold, I have told you before.
 Why if they shall say to you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not.
 For as the lightning comes out of the east, and shines even to the west; so shall also the coming of the Son of man be.
 For wherever the carcass is, there will the eagles be gathered together.
 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
 Now learn a parable of the fig tree; When his branch is yet tender, and puts forth leaves, you know that summer is near:
 So likewise you, when you shall see all these things, know that it is near, even at the doors.
 Truly I say to you, This generation shall not pass, till all these things be fulfilled.
 Heaven and earth shall pass away, but my words shall not pass away.
 But of that day and hour knows no man, no, not the angels of heaven, but my Father only.
 But as the days of Noe were, so shall also the coming of the Son of man be.
 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,
 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
 Then shall two be in the field; the one shall be taken, and the other left.
 Two women shall be grinding at the mill; the one shall be taken, and the other left.
 Watch therefore: for you know not what hour your Lord does come.
 But know this, that if the manager of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.
 Therefore be you also ready: for in such an hour as you think not the Son of man comes.
 Who then is a faithful and wise servant, whom his lord has made ruler over his household, to give them meat in due season?
 Blessed is that servant, whom his lord when he comes shall find so doing.
 Truly I say to you, That he shall make him ruler over all his goods.
 But and if that evil servant shall say in his heart, My lord delays his coming;
 And shall begin to smite his fellow servants, and to eat and drink with the drunken;
 The lord of that servant shall come in a day when he looks not for him, and in an hour that he is not aware of,
 And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth.
American King James Version×. In this section of teaching Jesus answers His disciples’ questions about when and how He will return to establish the Kingdom of God.
In verse 21 of that section of teaching Jesus tells them (and us) that His return will be preceded by a time of calamity and disaster worse than anything experienced since the beginning of the world and never to be equaled again (meaning it will be a one-time event occurring before His return). Note: You can read more about the events of that time of trouble in Revelation chapters 8 through 13.
What should you do about it?
In Luke’s version of this same prophecy Jesus gives his hearers a warning with some guidance: Be careful that neither the pleasures nor the anxieties of this life blind you to what is happening all around you and what you must do. He says be watchful, wary and pray that you may be considered worthy to escape all the calamities preceding His return (see Luke 21:34-36 Luke 21:34-36  And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come on you unawares.
 For as a snare shall it come on all them that dwell on the face of the whole earth.
 Watch you therefore, and pray always, that you may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
American King James Version×).
To be watchful applies to awareness of your own spiritual or moral condition, but can also apply to a good understanding of the prophecies God has made available to you through His prophets (including Jesus Christ). You can get started learning more about God’s words of prophecy by reading the study aid You Can Understand Bible Prophecy.
The second part of Christ’s warning to those listening to His prophecies is to pray that you may be considered worthy to escape.
What must I do to be considered worthy?
The answer is simple: You must change your ways, your thoughts and your attitudes, and conform them to the pattern of life outlined by God’s commandments and the example of Jesus Christ Himself. Our record of Jesus’ life shows Him to be a faithful and diligent keeper of the commandments. He says of Himself, “I have kept my Father’s commandments.” That’s a good place to start. Model your life after this example and work to make these changes meaningful and lasting through prayer, trial and application.
This instruction to actively follow Jesus' personal example is found in various places. Here are a few: “I [Jesus] have set you an example that you should do as I have done” (John 13:15 John 13:15For I have given you an example, that you should do as I have done to you.
American King James Version×). “Christ suffered for us leaving us an example that you should follow”(1 Peter 2:21 1 Peter 2:21For even hereunto were you called: because Christ also suffered for us, leaving us an example, that you should follow his steps:
American King James Version×). “Follow me [Paul] as I follow Christ” (1 Corinthians 11:1 1 Corinthians 11:1Be you followers of me, even as I also am of Christ.
American King James Version×).
You may have heard it said that all you need to do is utter the magic words “I believe in Jesus,” and you will thereafter be forever considered worthy. Don’t fall for it.
Not only must you believe that He existed (and still exists); not only must you believe that He was who He said He was; not only must you believe that He died to release you from the death penalty of your disobedience to God’s commands; but you must also believe the words that He taught and the instructions He gave, and actively follow the example He gave you.
Jesus said: “Don’t think I have come to abolish the law or the Prophets; I have come not to abolish them but to fulfill them” (Matthew 5:17 Matthew 5:17Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill.
American King James Version×, New International Version). He goes on to say that anyone teaching against the commandments will be considered as the least by those who are in the Kingdom of God. Could it also be that those called the least are also those who have proven themselves unworthy?
