Spurgeon's A Puritan Catechism:

19 Q. Who is the Redeemer of God's elect?

A. The only Redeemer of God's elect is the Lord Jesus Christ (1 Tim. 2:5), who being the eternal Son of God, became man (Jn. 1:14), and so was and continues to be God and man, in two distinct natures and one person for ever (1 Tim. 3:16; Col. 2:9).
