So the anger of the Lord was kindled against Israel, and he gave them over to plunderers, who plundered them. And he sold them into the hand of their surrounding enemies, so that they could no longer withstand their enemies. Whenever they marched out, the hand of the Lord was against them for harm, as the Lord had warned, and as the Lord had sworn to them. And they were in terrible distress.
Many believers act as though God doesn't care about our sin. "After all," one might think, "Jesus has already paid for my sin so why does it matter?" This attitude leads many Christians today handle their sin with a kind of a wink and a smile, but not so with God. God hates sin! He is Holy, pure, and perfect. Sin is an affront to His very nature. It is rebellion against Him. It is an insult to Him. God never deals with sin lightly. He never overlooks it. The atonement proves this. God's unwillingness to overlook our sin is why Jesus had to die. The only way any of our sins could be forgiven was for God's wrath against those sins to be fully satisfied. God poured out the punishment for our sins on Jesus as our substitute on the cross. But do not be so mistaken as to think that just because the eternal punishment of our sin has been dealt with that God no longer cares about your sin or that there will be no consequences to your sin.
The above passage from Judges reveals that God set His face against His people because of their sin. He turned against them and put them in great distress. Don't think He won't do the same to you if you harbor sin in your life and in your heart. But even here there is good news, for our God is good. Even as God punished His people He showed them mercy and felt compassion for their suffering. The New Testament teaches that God disciplines believers like a Father disciplines the son whom He loves (Hebrews 12:5-7). He punishes us to bring us back to Himself. Punishment isn't reserved for the lost, rather redemptive punishment shows that you are a beloved child of God.
Does it seem as though God has been against you lately? Search your heart and your life for unconfessed sins and sins you have asked forgiveness for but aren't turning away from. Don't dare to ask God to forgive you of some sin, while having no intention to stop committing it. Instead take Scripture's advice. Fear God and fear His punishment (Proverbs 1:7, 3:7, & 16:6). Even though we know God's discipline is merciful and compassionate, it is still dreadful. So turn from the sin in your life and double your commitment to walk closely with the Lord.
