Many people, including a lot who believe in God, have stated that we cannot prove that God exists. They come to this conclusion because unlike animals, vegetables and minerals, God is not a being that can be seen, measured, weighed, put on display or examined. As they say, "You can't put God in a test tube." Nevertheless, the proof that He exists has always been patently obvious from the very first day He created the world.Nearly two thousand years ago, in the first chapter of his letter to the Romans, the apostle, Paul, wrote, "From the time the world was created, people have seen the earth and the sky and all that God has made. They can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse whatsoever for not knowing God." (Romans 1:20 New Living Translation.)Well, if God's known invisible qualities were obvious enough in Paul's day for people to be without excuse for not believing in Him, how much less excuse is there today for not believing in God? Man is discovering more and more of God's extraordinarily amazing invisible resources all the time.
