The truth is not always popular, especially when it does not favor the selfish, but the truth remains constant!

...He was a murderer from the beginning, not holding to the truth, for there is no truth in him.
When he lies, he speaks his native language, for he is a liar and the father of lies. (John 8:44)
A lying tongue hates those it hurts, and a flattering mouth works ruin. (Proverbs 26:28).
For where jealousy and selfish ambition exist, there is disorder and every evil thing. (James 3:16).
Pride only breeds quarrels, but wisdom is found in those who take advice. (Proverbs 13:10).
