Truth seems up for grabs in our confused culture.
It is possible to speak truth in a nasty way or for improper motives, which is why Scripture reminds us to speak the truth in love.
God is the ultimate source of truth. Actually, he is truth, so he defines reality and he never said, "Don’t speak the truth." So, speaking truth is not an act of hate, as incredibly some now claim.
It may seem harsh, for example, to call something error, wrong, sin, but if true, it creates an opportunity for change, correction, forgiveness, redemption > hope.
Without truth, there is no hope.
