Creation testifies

“For since the creation of the world God’s invisible qualities – His eternal power and divine nature – have been clearly seen, being understood from what has been made, so that men are without excuse.” Romans 1:20
Creation testifies two things (in particular) about God:His eternal power and His divine nature. His power as the Creator is obvious. Nothing in this world has come into existence ‘by chance’. People talk about the anthropic principle, that the earth seems to be in an optimal configuration for man to exist. Of course, if they would only read the Bible, they would realise that God created it this way, and gave man dominion over it (Gen. 1:28).
Yet, God’s love towards us is not shown perfectly in nature. This is the result of the Fall. When sin came into the world, so too did injustice in nature. Life became a battle for survival. Some animals became predators, and plants and animals developed poisons, thorns, claws, and teeth to harm each other. This is why the creation itself looks forward to the day of redemption (Rom. 8:20-22), when the wolf will lie down with the lamb (Isa. 11:6, Isa. 65:25).
When we look at creation, we may not see God’s love towards us, but we are without excuse as to His existence. We have a responsibility to Him, as His creations. To say that He does not exist and that His creation came about by random chance, is a great insult, when the truth is so plainly evident.
