Does God go around punishing His children? If something bad happens to a Christian, is that proof that God is punishing him? Let's look at the entire passage we quoted last time:
Heb 12:5 And you have forgotten the exhortation which speaks to you as to sons: "My son, do not despise the chastening of the LORD, Nor be discouraged when you are rebuked by Him;
6 For whom the LORD loves He chastens, And scourges every son whom He receives."
7 If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten?
8 But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons.
Verse 5 says "when," not "if," you are rebuked by God.
Verse 6 says that God scourges "every" son whom He receives.
Verse 8 says that "all" Christians receive this chastening, and if you don't, you are not really saved.
But aren't Christians delivered from the wrath of God? Yes, they are. Verse 5 explains that God is talking to His sons, not His enemies. A good father will chasten his children FOR THEIR OWN GOOD. God does not pour out His wrath on those who have accepted Jesus Christ as Saviour. But God, as a loving Father, does correct His children for their own good.
