"Our Lord said, "Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven"(Matt. 10:32). What is it to confess Christ?
It is to have an understanding in the mind of WHO Christ is, WHAT Christ did, and WHERE Christ is. "The Son of God has come and given us an understanding...
It is to believe Christ in the heart (Rom. 10: 9-10), to receive Christ with a sincere and genuine heart love, and committal as Lord and Saviour, Prophet, Priest, and King.
It is to confess Christ openly and publicly in believer's baptism. "He that believeth and is baptized shall be saved." Baptism does not save nor add anything to the Saviour's work; but it is a confession of, identification with, and testimony of the death, burial, and resurrection of our Lord, and our own death to sin and resurrection TO WALK WITH HIM.
It is identification with the church of our Lord Jesus, the people who love Him, and the preachers who preach His gospel of free and sovereign grace. Paul said to Timothy, "Be not ashamed of the testimony (gospel) of our God, nor of me His servant, but be ready yourself to partake (be identified) of the afflictions of the gospel." Where the gospel is preached, where the true people of God meet to worship, where the name of Christ is worshipped and exalted, THERE I WANT TO BE! And if I truly love Christ and confess Christ, THERE I WILL BE!
It is to speak of Christ daily in conversation, prayer, and as a faithful witness.
