Ephesians 4:14-15 (KJV)
That we . . . speaking the truth in love, may grow up into him in all things, which is the head, even Christ.
Just because something is true doesn’t it should be spoken.
May our speech be filled with truthful but loving words:
Philippians 4:8
. . . whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report.
