As such, the Bible becomes our source of morality because the Bible is the very Word of God in written form ( Cf2 Timothy 3:16; 2 Peter 1:21). If the Christian wants to know God’s will, he turns to the Bible. If the Christian wants to discern right from wrong, he turns to the Bible. The Christian is aware that at the end of the day he will come face to face with his creator and will be expected to give an account of his life on earth. God is a necessity for morality. Immanuel Kant in his ethical works affirms that morality requires God, for without God nothing really matters. (ethicalrealism.wordpress.com/2010/01/28/kants-argument-for-faith-in-god/). God becomes the basis for moral behaviour and without God everything becomes permissible.
Without an absolute standard, morality would be relative and dependent on each individual. But morality is not a human invention; it flows from the nature of God, who is eternal and unchanging. Therefore, as much as we may want to, we cannot determine what is right and wrong on our own. Our Creator, the Source of all truth, has revealed what we need to know of right and wrong in His Word.(
