"The Bible tells us that God is the Creator of all things, and therefore, all things belong to Him (The earth is the Lord’s and the fullness thereof, the world and those who dwell therein, Psalm 24:1). Thus, God as the Creator has the right to define absolute standards of behavior.
Dr. Greg Bahnsen (1948–95) states, “What does the unbeliever [person who rejects the Biblical God] mean by ‘good,’ or by what standard does the unbeliever determine what counts as ‘good’ (so that ‘evil’ is accordingly defined or identified)? What are the presuppositions in terms of which the unbeliever makes any moral judgments whatsoever?”
Although unbelievers may classify actions as good or evil, they do not have an ultimate foundation for defining what is good and evil." AIG
