I will offer a sacrifice... (Ps 54:6)

Psalm 54 describes the life that is wholly devoted to God, in itself also bringing a prophecy of Christ. Though "strangers turn against me, and cruel men want to kill me," (v. 3) "the Lord will support me." (v. 4) Often we have this idea that if I devote my life to the Lord, nothing bad will ever happen in our lives. Then at the slightest hint of trouble, we "gnaw our tongues [in] pain and...curse the God of heaven," (Rev. 16:10-11). Unfortunately, this is simply not the case. Even a brief skimming of the gospels will show that the life of Jesus was full of strife and persecution. He was forced from his hometown and almost thrown over a cliff (Luke 4:28-30), He was accused of being possessed (Mark 3:22), He was beaten and spat upon (Matt. 26:67), He was mocked, being call gluttonous and a drunk (Luke 7:34), and many other horrible things. We are even told, as His followers, to expect the same treatment (Matt. 24:9).
As these terrible things continue to affect us, offering our broken spirit as a sacrifice (Ps. 51:17) is the way God is allowed to "save [us] from all...troubles," (v. 7). In this way, because we are in Christ, judgment will pass over us and we will "see [our] enemies defeated." (v. 7)
