Truth is bitter and so must be spoken in love. Bitter truths are best communicated when packaged like sandwich or capsule rapped up in-between compliments.
“Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.” – Galatians 6: 1
“But speaking the truth in love, may grow up into him in all things, which is the head, [even] Christ.” – Ephesians 4: 15
“Let your speech be always with grace, seasoned with salt, that ye may know how ye ought to answer every man.” – Colossians 4: 6
