This is the same “false” (8267) “witness” (5707) we find in the ten commandments.
(Exodus 20:16 KJV) Thou shalt not bear false (5707) witness (5707 against thy neighbour.A lie is incompatible with truth. A half truth is a lie. This goes to the heart of Christian character and the character of God. A few verses ago it said this was abomination to God.
So? A Christians we believe in absolute truth. Obviously there are times when we must seek the lesser of two evils or the better of two goods but that does not take away the fact that truth exists. We are expected to be living witnesses to it. We are expected to be different from the culture that we are immersed in.
