Isaiah 49:3

3. Thou art my servant, O Israel Already has it been seen, (Isaiah 42:1,) that Israel as a nation formed with our prophet a basis idea contained in the terms, servant of Jehovah; then, true to his calling and faithful to Jehovah, Israel became the central idea in that term; and, lastly, Israel, as God’s personal servant, is found in the idea of the true Israel’s highest headship, the Messiah. In this last sense is the word servant of Jehovah, or the Church and its Head in one, to be taken here.

In whom I will be glorified “Glorified” through his instrumentality the consecrated Church and its Head in saving the world. The innermost holy Israel as an agency is personified in the term “servant.” A like example of appealing to a representative quality is in Matthew 16:18, “Thou art Peter;” representing the Peter, on the one hand, a rock-like man confessing Christ as Son of the living God, and on the other hand, Christ, the eternal One confessed; and both together concreted into one term, namely, Confession, the ROCK on which the God’s Church is built.
