Hebrews 12:6 says, “For whom the Lord loves he chastens, and scourges every son whom he receives” (KJV).
Another word for “chasten” is “discipline.” The passage goes on to quote Proverbs 3:11-12, which says, “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.” Proper discipline is a proof of love.
Throughout Scripture, God portrays Himself as a Father. Those who have received Jesus as Savior are His children (John 1:12; Galatians 3:26). He uses the analogy of father/son because we understand it. He compares Himself to a loving father who not only blesses but disciplines His beloved children for their own good. Hebrews 12 goes on to show that those who do not receive God’s discipline are not legitimate children (verse 8). A loving father carefully watches his son, and when that son defies his orders and heads for danger, the father disciplines him to keep him safe. God does that with us. When a born-again child of God heads for sin or refuses to resist temptation, our Heavenly Father brings chastening into his life to direct him back to holiness.
Chastening can come in the form of guilty feelings, unpleasant circumstances, loss of peace, relationship fractures, or any number of negative consequences for choosing sin. Sometimes, the chastening of the Lord can be physical illness or even death (1 Corinthians 11:30).
Often, people ask if God is “punishing” them for wrong choices in the past. All our punishment for sin was exhausted upon Jesus on the cross (Romans 5:9). The wrath of God was poured out on Him so that for those who are “in Christ Jesus” (Romans 8:1) no wrath remains. When we give our lives to Christ, our Substitute for sin, our sin is forgiven and God remembers it no more (Hebrews 8:12; 10:15-18). However, often, our wrong choices in the past have brought about unpleasant consequences now. God does not necessarily remove the natural consequences of sin when we repent. Those consequences are tools God can use to teach us, to prevent us from repeating the same mistakes, and to remind us of God’s grace.
Examples of chastening are found throughout the Bible. The Israelites were continually disobeying God’s commands (Numbers 14:21-23; Judges 2:1-2; 2 Kings 18:12). He was patient with them, He sent prophets to plead with them, and He warned them many times. But when they dug in their heels and embraced idols or evil practices, God brought chastening upon them in the form of plagues or enemy attacks (Jeremiah 40:3). He still loved them, and in His love He could not allow them to continue in behavior that would destroy them.
There are many examples of personal chastening in the Bible, as well, even upon those in whom the Lord most delighted—Moses (Numbers 27:12), David (1 Chronicles 28:3), and Solomon (1 Kings 11:11), to name a few. Notice that, although these men made mistakes and were chastened for them, God did not stop loving or using them. He brought discipline appropriate to the crime, but always forgave the truly repentant heart. God always restored the relationship.
When we sin, we can expect that our loving Heavenly Father will not let us get away with it. Because He loves us, He desires us to live holy lives (1 Peter 1:15-16; Romans 8:29). If someone professes to know Christ but is living a lifestyle of unrepentant sin and claims to “feel fine about it,” with no qualms, then that person is not a legitimate child of God (Revelation 3:19; Hebrews 12:5-11; Job 5:17; Psalm 94:12; I John 3:4-12). God “punishes everyone he accepts as a son” (Hebrews 12:6).
