Tit 2:15 These things speak, and exhort, and rebuke with all authority. Let no man despise thee.
Speak the truth of God, and exhort, to encourage, strengthen. To take someone aside to straighten out their thinking and to put them back in the right path. The opposite of this I suppose would be to gossip about a person, to tear them down. We are to build up the body of Christ through sound teaching and instruction, no divisions unless a person opposes the truth and causes strife. Some must be rebuked, convicted of wrongdoing with meekness and love, but also with the authority of the word of God. We are not to be ashamed of God's word, nor of our service to him. How often have we seen someone corrected and restored? This is a lovely thing, but more often we see people talked about in gossip and often they feel the shame, but it comes from the devil. The devil seeks to kill and destroy. God sent his Son to restore that which was lost. We are to be in the place of Jesus, restoring people, bringing them into godly conviction so that they can walk in the light of God.
