Gibbs, Jeffrey A. “Matthew 10:32-33: Confess Jesus Boldly." Matthew 1:1-11:1. St. Louis: Concordia Publishing House, 2006, pp. 533-535.
In Matthew 10:32-33 Jesus affirms the need and effectiveness of confessing him boldly. Gibbs applies this to all Christians in every age (Gibbs 2006, 533). He is clear, referencing Romans 10:0, that the confession does not earn merit before God but rather reflects the attitude of the heart which has received God's grace (Gibbs 2006, 534). Denial of Jesus has terrrible consequences, and, according to Gibbs, must be stopped with repentance and faith.
