A Christian is someone who believes the promises of Scripture alone, that eternal salvation is found through faith alone in Jesus Christ alone by grace alone for the glory of God alone.
Having been born again through the Holy Spirit, and having confessed that he or she is a sinner in the eyes of God without hope apart from Christ, having turned away from sin in repentance and bowed the knee in surrender of their life to the Lordship of Christ, believing that His sacrificial death on the cross washes away their personal sin, joined in union with Him by faith, such that His Righteousness is their Righteousness, the believer now takes the step of obedience to the command of Jesus to be immersed in water as a symbol of dying to one’s old life, dying with Christ, being buried with Christ, to be raised to new life with Christ as a new creation. If anyone is in Christ, he is a new creation. The old has gone, behold! the new has come! (2Cor 5:17)
The Lord Jesus commanded baptism for His disciples, He set the example of baptism by getting baptized Himself, and He practiced baptism in His earthly ministry. Baptism is how believing followers become disciples, for the act of baptism makes public confession to the world that “I have decided to follow Jesus, no turning back, no turning back.” It is the making of covenant between the believer and God through Jesus Christ, that He will be his or her God, and he or she will be His child, to live for Him, for His honour and glory.
Do you confess faith in Jesus Christ as your personal Lord and Saviour, having repented of your sin and surrendered your life to Him, trusting in His cross alone to wipe away your sin debt before God? Do not delay! Get baptized in obedience to your Lord!
"All authority in heaven and on earth has been given to Me. Go therefore and make disciples of all nations, baptizing them in the Name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the Age." —the risen Lord Jesus Christ (Matthew 28:18-20)
