God does hate, although His hatred is real and righteous, it is not like human hatred; it flows from His holy nature and is always just. He hates sin and those who persist in sin while, at the same time, He is love, and His love is shown in delaying His wrath and offering salvation through Jesus Christ. Through Jesus’ sacrificial death, God made a way for sinners to escape His just judgment without compromising His justice. Therefore, God’s hatred of sin and His love for sinners work together: His justice punishes sin, and His love provides a path to mercy.
God’s hatred of sin means that He hates sin and those who participate in it. It is a just hatred because God is holy and is opposed to all sin. John says that unrepentant sinners currently have His wrath hanging over their head (John 3:36b). However, God gave a way of escape from His wrath. God is, truly, love. However, His is not love that ignores sin. That would be wicked since He would allow sin to go unpunished. Instead, He maintains His justice while lovingly providing a way to escape it (Romans 3:21–26).
For unbelievers: flee the wrath to come (Matthew 3:7b). Jesus said that anyone who comes to Him will not be cast out (John 6:37b). As the Son of God, He hates sin and is the one bringing God’s wrath! (Revelation 19:15b). However, right now He offers Himself as the one way of escape (John 14:6). All who repent of their sin and trust in Jesus (Romans 10:9) will escape the final wrath that will consume all sinners once-and-for-all (Romans 5:9).
For believers: let us not grow complacent and forget that we were saved from God’s wrath. God considers us righteous, but not because of anything we did. Instead, we have salvation because God is love and extended mercy to us through His Son. There are many among our families, friends, and coworkers who are currently under God’s anger. When they die, they will be cast into Hell. If that happens, God will be just. However, He is also merciful. Tell everyone you know about God’s burning hatred of sin. Warn them, plead with them, and pray for them. Tell them about God’s great gift of love (Romans 6:23b), His Son!
