Romans 1:19-20
Since what may be known about God is plain to them, because God has made it plain to them.
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.
One day I was agreeing with my son, an atheist, how God's person is unknowable by merely natural means. But He has chosen to reveal Himself to us through His Word and all the natural things He made. I asked him how he would answer a friend who denied that my son even had a father, but just made him up? His reply was that he would show his friend the things his Dad had made, like the house. So I pointed out that it would be foolish to suggest that natural, environmental processes over a long period of time could produce a beautiful house suitable for dwelling in. It is equally foolish to deny the existence of a Creator who made this world suitable for our living here. This was answered by a period of silence.
