^3:19 I correct and discipline everyone I love. Take this seriously, and change the way you think and act.

I CORRECT and DISCIPLINE everyone I love.

The unwanted and unloved seldom have anyone around to discipline them. Thus we should be thankful that God is around to discipline us. John 14:19-21 says we are loved by God and He will disclose Himself to us. So if we are sons of God, then as a Father He disciplines us (Hebrews 12:4-13 and Proverbs 3:12). The "DISCIPLING us" is for our growth to bring us to a place of abundance according to Psalm 66:8-15. We are to judge ourselves, and if we judge rightly then the Lord disciplines us (1 Corinthians 11:28-32).

Take this seriously,

A zealous person is NOT lukewarm, they are on FIRE! (1 Corinthians 15:58).

and change the way you think and act.

The very last thing an unbeliever wants to do is CHANGE. The very last thing a believer wants to do is CHANGE. Why?

It leads to exposure ("nakedness" in the previous verse 18) as to who you really are. BUT TO CHANGE has its good points!
