What then? If some did not believe, their unbelief will not nullify the faithfulness of God, will it? May it never be! Rather, let God be found true, though every man be found a liar, (Romans 3:3-4a NASB)
The unbelief of an atheist doesn’t nullify GOD in any measure or implication; it only minimizes the atheist’s mind, hardens the atheist’s heart, limits the atheist’s life, and reduces the atheist’s usefulness – and ultimately proves the atheist to be a fool.
The fool has said in his heart, “There is no God.” (Psalm 14:1a NASB)
PSYCHOLOGY: the study of how sin – and the menace, mayhem, and malfunction it produces – is manifested through the thoughts, feelings, and behaviors of broken human beings, and how this influences and affects our lives and relationships.
The evil of humankind toward and against itself is more than enough evidence to eagerly embrace the existence of a compassionate GOD and the imminent necessity for the salvation from ourselves by His irrefutable grace offered through His incarnate Son, Jesus.
