Jesus said not to worry about our life—what we will eat or drink, about our body and what we will wear—because life is more than all of that (Matthew 6:25 Matthew 6:25Therefore I say to you, Take no thought for your life, what you shall eat, or what you shall drink; nor yet for your body, what you shall put on. Is not the life more than meat, and the body than raiment?

Life gives us ups and downs—sometimes we win and sometimes we lose. Our best-laid plans can go astray. What Jesus was being careful to explain was that the item of first importance in our minds and lives ought to be eternity, and the Kingdom to come (Matthew 6:33 Matthew 6:33But seek you first the kingdom of God, and his righteousness; and all these things shall be added to you.

Jesus went on to say the things we need will be added. Some believe that Christians should not work hard or save money. They believe Jesus recommended poverty, but that misses the point entirely. Jesus Himself was a trained carpenter or stone mason (Mark 6:3 Mark 6:3Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him.

The Bible speaks against laziness, recommending thrift and planning for the winter ahead (Proverbs 6:6-11 Proverbs 6:6-11 6 Go to the ant, you sluggard; consider her ways, and be wise: 7 Which having no guide, overseer, or ruler, 8 Provides her meat in the summer, and gathers her food in the harvest. 9 How long will you sleep, O sluggard? when will you arise out of your sleep? 10 Yet a little sleep, a little slumber, a little folding of the hands to sleep: 11 So shall your poverty come as one that travels, and your want as an armed man.
