Revelation 3:19 NIV

1 Corinthians 11:32 NIV
Nevertheless, when we are judged in this way by the Lord, we are being disciplined so that we will not be finally condemned with the world.

Hebrews 12:5-11 NIV
And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says, “My son, do not make light of the Lord’s discipline, and do not lose heart when he rebukes you, because the Lord disciplines the one he loves, and he chastens everyone he accepts as his son.” Endure hardship as discipline; God is treating you as his children. For what children are not disciplined by their father? If you are not disciplined—and everyone undergoes discipline —then you are not legitimate, not true sons and daughters at all. Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of spirits and live! They disciplined us for a little while as they thought best; but God disciplines us for our good, in order that we may share in his holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it.

Proverbs 3:11-12 NIV
My son, do not despise the Lord’s discipline, and do not resent his rebuke, because the Lord disciplines those he loves, as a father the son he delights in.

Revelation 2:5 NIV
Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place.
