In order to prove a point, win an argument, silence opposition or appear intellectually superior, many today are claiming that, in our post-truth era, it is incomprehensible and intolerable to speak of a definite “right or wrong,” “truth or error,” “black or white.” Everything today is relative, and seemingly growing more and more relative.
The biggest problem with that is that the Bible does not support such a mindset. The Bible makes abundantly clear that there is a plain difference between “good and evil,” and it is not only possible to “know” the difference (Deut. 1:39), but it is possible to “discern” and “reason” about the difference (Heb. 5:14). God identifies that which is right and good (according to His divine standard), He has communicated such to us, and He has given us a mind to understand it. It is possible to “know” truth (John 8:32).
It is possible to “understand” truth (Acts 8:30; Eph. 3:4). It is possible to “reason” about truth (1 Sam. 12:7; Acts 17:2). It is possible to “err” from truth (Matt. 22:29; Jas. 5:19). God calls us to “reason” (Isa. 1:18). Use your brain!
