Why would anybody, in their right mind, delight in receiving discipline? Simply stated, because God commands that we receive discipline.
If you receive discipline from God, you can be assured that He loves you, Proverbs 3:12 (ESV) —12 for the LORD reproves him whom he loves, as a father the son in whom he delights.
God’s discipline is not for punishment (that was accomplished on the cross). Rather God’s discipline is designed to transform us. This can be gleaned from Hebrews 12:10–11 (ESV) — 10 For they disciplined us for a short time as it seemed best to them, but he disciplines us FOR OUR GOOD, that we may SHARE HIS HOLINESS. 11 For the moment all discipline seems painful rather than pleasant, but later it yields the PEACEFUL FRUIT OF RIGHTEOUSNESS to those who have been TRAINED by it.
Friend, are your days a struggle? The only response to these hardships is submissive, grateful grace. Hebrews 12:9 (ESV) — 9 Besides this, we have had earthly fathers who disciplined us and we respected them. Shall we not much more be subject to the Father of spirits and live?
