Two men become stranded on a remote island. As they explore the island they come upon a sandcastle with towers, buttresses and a drawbridge. The design of the castle is amazingly intricate.
One man comments, "It is amazing what time and the ocean can create. The small rocks and seashells on the shore must have got caught in eddies and swirled around and chiseled out that castle. There were a few palm leaves floating by that scribed out the little lines that look like bricks. We are alone here and there is no need to consider anything else."
The other man looked at him incredulously and said, "No, that castle was created by another intelligent being with a clear intent of design, we are not alone."
Rom 1:19-25
19 Because that which may be known of God is manifest in them; for God hath showed it unto them.
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
