What does Revelation 22:12 mean?

Again, Jesus delivers a promise to return "soon," which is from a Greek word that more accurately means "quickly." This has more to do with how Jesus is coming than when. His return will be sudden and unpredictable (Matthew 24:36).

Also, this promise includes the fact that God will recompense each person according to his deeds. Faithful believers may anticipate rewards, but unbelievers must face punishment. When the apostle Paul neared execution, he looked forward to receiving the crown of righteousness that the Lord would award to him. He added that he would not be the only one to receive this reward. He said all who have loved Jesus' appearing will also receive the crown of righteousness (2 Timothy 4:8). Other crowns (James 1:12; 1 Peter 5:4) are promised to faithful believers that will likely be awarded at the Judgment Seat of Christ.

Second Corinthians 5:10 states: "For we must all appear before the judgment seat of Christ, so that each one may receive what is due for what he has done in the body, whether good or evil." This is often referred to as the "Bema seat," and is not the same as the judgment given to those who reject Christ. Unbelievers will be judged at the great white throne and be sentenced to eternal suffering in the lake of fire (Revelation 20:11–15).
