What the Bible says about Christ as God's Servant
(From Forerunner Commentary)
The reference to Christ as God's Servant here is reminiscent of Acts 2:18 (and Joel 2:29), where God says He will pour out His Spirit "on My menservants and on My maidservants." Those in God's New Testament church act as God's servants, under Christ, the Head of the church, to preach the gospel "in all the world as a witness to all the nations, and then the end will come" (Matthew 24:14). Only about thirty verses later, in Matthew 24:45-51, Jesus again makes use of the servant metaphor, this time in the Parable of the Faithful and Evil Servants. The working servant is rewarded at Christ's return, but the evil one, convinced that "My master is delaying His coming," finds himself "cut . . . in two."

Peter's Trumpets Message—on Pentecost
Here the Branch is called God's Servant, taking away iniquity in one day. This is exactly what Christ did, and is reminiscent of Paul's description in Philippians 2:7: "But [Christ Jesus] made Himself of no reputation, taking the form of a servant. . . ."
