What does Revelation 14:12 mean?
Those who refuse to worship the beast will be under intense persecution. Prior verses indicated that those who rejected his mark would be ostracized at best, and martyred at worst (Revelation 13:16–17). This verse encourages them to patiently withstand the persecution. They are saints; that is, believers who are separated unto God. They obey God, not the beast, and their faith is in Jesus.Genuine faith in Jesus shows up when it is tried. Peter described such faith as "more precious than gold that perishes though it is tested by fire" (1 Peter 1:7). He predicted that genuine faith will "be found to result in praise and glory and honor at the revelation of Jesus Christ" (1 Peter 1:7).
Perhaps those who are called saints in this verse are Jewish believers. It is said they keep God's commandments. This may be a reference to the Ten Commandments that God gave specifically to Israel. When He gave Israel the Ten Commandments, He said, "I am the LORD your God, who brought you [the Israelites] out of the land of Egypt, out of the house of slavery" (Exodus 20:2).
