It's a simple and fair question. But the answer defies human logic, reasoning and experience.
We experience things through our physical senses. Our eyes capture the light reflected from physical objects. Our ears pick up the vibrations from sound waves. Our fingertips gauge the texture and hardness of the things we touch.
We live in a physical world with its four known space-time dimensions of length, width, height (or depth) and time. The God of the Bible, however, dwells in a different dimension—the spirit realm—beyond the natural perception of our physical senses. It's not that God isn't real; it's a matter of Him not being limited by the physical laws and dimensions that govern our world (Isaiah 57:15 Isaiah 57:15For thus said the high and lofty One that inhabits eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.

American King James Version×).
Notice what the Scriptures reveal about this God who is not bound by space and time.
Jesus Christ as a human being had a physical body. Like ours, His was subject to injury, pain and death. The four Gospels record that He was scourged and crucified. Several of His followers took His brutalized body, wrapped it in strips of linen and sealed it in a tomb. There was no doubt Jesus was dead. His body lay in the tomb for three days and three nights, watched over by a detachment of guards.
But it was not to remain so. A minor uproar ensued at the end of the three days when some of His followers came to the tomb—only to find it empty. They would be in for an even greater surprise!
That evening His disciples gathered in a room, with the doors firmly shut because they feared for their lives, when “Jesus came and stood in the midst, and said to them, ‘Peace be with you'” (John 20:19 John 20:19Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the middle, and said to them, Peace be to you.

The resurrected Jesus was no longer bound by physical factors. He effortlessly entered a closed room and revealed Himself to His disciples. They recognized the physical impossibility of a fleshly body passing through walls. Eight days later He repeated the miracle for the benefit of the disciple Thomas, who hadn't witnessed the earlier appearance (John 20:26 John 20:26And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the middle, and said, Peace be to you.

Scripture reveals that God lives outside the bounds of time as we know it (Isaiah 57:15 Isaiah 57:15For thus said the high and lofty One that inhabits eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.
American King James Version×). We read that our awesome destiny was planned “before time began” (2 Timothy 1:9 2 Timothy 1:9Who has saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,
American King James Version×; Titus 1:2 Titus 1:2In hope of eternal life, which God, that cannot lie, promised before the world began;
American King James Version×) and “before the creation of the world” (Ephesians 1:4 Ephesians 1:4According as he has chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
American King James Version×; 1 Peter 1:20 1 Peter 1:20Who truly was foreordained before the foundation of the world, but was manifest in these last times for you,
American King James Version×, NIV).
“By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible” (Hebrews 11:3 Hebrews 11:3Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
American King James Version×, NIV). In other words, the physical universe we see, hear, feel and experience was created not from existing matter, but from a source independent of the physical dimensions we can perceive.
This does not mean God the Father and Jesus Christ never reveal Themselves to people. The Scriptures are a chronicle of God's interaction with—and care and concern for—men, women and children through the centuries.
Many people reject the Bible, the Gospels in particular, because it describes many miraculous occurrences—dramatic healings, resurrections, fire from heaven and spectacular visions, to name a few. They believe these things are impossible because they defy human experience and the laws that govern our physical existence. They thus conclude that biblical accounts of such things cannot be true.
Regrettably, they fail to consider that God the Father and Jesus Christ can operate beyond the bounds of the physical laws that govern the universe. A God who can bring the universe into existence can certainly perform miracles such as those found in the Scriptures!
Where does this leave us? Will we believe the many witnesses God has provided, or will we insist on some kind of proof He provides us personally before we believe? Jesus' words to Thomas in John 20:29 John 20:29Jesus said to him, Thomas, because you have seen me, you have believed: blessed are they that have not seen, and yet have believed.
American King James Version×are also clearly intended for us: “Because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed”!
