The Doctrine of God - Anthropological Argument for the Existence of God

"Which show the work of the law written in their hearts, their conscience also bearing witness and their thoughts the mean while accusing or else excusing one another;)" (Romans 2:15)

The existence of man as a moral and intellectual being is an argument for the existence of a moral and intellectual being called God. This is true because man was created in the image and likeness of God (Gen. 1:26), and even after the Fall he has the law of God written in his heart.
Illustration: When people follow God, they often follow the God they see in the lives of others. Paul taught the Corinthians to follow him as he followed the Lord (1 Cor. 11:1).
Application: So today, Christians ought to be careful to reflect the character of God in their lives and not become a stumbling block to the gospel.
