 Well, that starts by trusting Him enough to repent of your sins and to confess the name of Christ before others. Christ doesn't want a secret disciple. He wants you to confess with your mouth that He is your Lord and that you believe He is the Christ, the Son of the living God. And after you've repented and made that confession, God wants you to be baptized into Christ where God cleanses you with the blood of Jesus and makes you into one of His children.
