The Bible says "Put me (God) to the test . . ." (Malachi 3:10). It also encourages us to test all things (1Thessalonians 5:21). Our heavenly Father says that true faith is based on evidence (Hebrews 11:1). The faith we have that the sun will rise tomorrow, though we have not yet seen it, is because we have seen it rise day by day in our lives.
Note the following analogy as it related to the existence of God. If someone took you to an island and told that nobody had ever been there before, what would you know if you found the following? As you reached the shore of the island, you saw a trail of bricks (like those to build a house) going off into the interior of the island.
One proof of God
At the beginning of the trail was one brick. Ten feet away was a pile of two bricks, laid neatly together to form a square. Ten feet farther away there are three bricks, in a neat pile. Yet another ten feet showed four bricks, in a neat cubic stack. Every ten feet you see five bricks, six bricks, seven bricks, on into the interior of the island in neat piles ten feet apart.
When you saw this, who could convince you that nobody had ever been to this island before? Could they convince you that the seas had roared from time to time and finally coughed up these bricks, neat rectangular solids? Those millennia of high tides had washed these bricks into neat stacks and numerically sequenced them through the millions of years. Then they would have you believe that you happened on this situation in the right decade before another storm came up and scattered them?
What would you know? You would know that someone does exist that visited the island. The brick trail tells you so. Why does it? The two things that give you knowledge that someone had been there are structure and a numerical sequence. It is such facts that can lead us to God.
You know that structure requires someone, like God, to structure it. The rectangular solids like a brick require an equal spacing of the piles require a hand to space them in such a structure, neat piles require someone to pile them neatly.
The bricks demand a brick maker (God) who gave them all their uniform rectangular solid shape. The spacing of the brick piles ten feet apart would demand a mind to measure and space them. Someone stacked the neat piles. Structure demands a builder. The structured trail demands a builder who made this trail.
Furthermore, we realize that someone had to count out the bricks in order for each pile. Numerical sequence demands a mind that can count (1, 2, 3, 4, etc.) and that is rational and not random. You would know that someone had been there!
Such bricks and their arrangement in sequences and patterns could not have evolved from the mindless process known as the theory of evolution! Only a fool could be convinced they just happened into that numerical configuration over millions of years. There had to a mind behind the arrangement of the bricks, a mind we know as God who indeed does exist!
