You are the Christ, the son of the living God (Mt. 16:16).
Scripture also has many references to the importance of confessing the name of Christ. For example, in Romans 10:9, if thou confess with thy mouth the Lord Jesus, and believe in thy heart that God hath raised him up from the dead, thou shalt be saved. Heretics have misinterpreted verses such as these to spread the pernicious error that merely accepting Christ as your “personal Lord and Saviour,” and superficially confessing that He is Lord, would by that fact, number you among the “saved”.
The truth however, is far deeper than that heresy. The very fact that the Scriptures teach us the need of confessing Jesus as Lord points to the necessity of good works in order to be saved. This does not in any way reflect the neo-Pelagian heresy that we are somehow saved by our own initiative by reaching out to God, who in turn gives us grace, for Scripture also teaches us no man can say ‘Jesus is Lord’, but by the Holy Ghost (1 Cor 12:3). However, this is contrasted with the other extreme of thinking that the human will is so damaged due to sin that it loses its autonomy and God has to move it like how we move an inanimate object. This latter extreme of the loss of free will due to original sin, a doctrine of the Calvinists, is unbiblical (cf. Mt. 23:37, Acts 7:51) as well as solemnly condemned by the Council of Trent.
