"So then faith cometh by hearing, and hearing by the word of God." (Romans 10:17)
"Therefore I said to you that you will die in your sins; for if you do not believe that I am He, you will die in your sins." (John 8:24)
Turn from your sins "Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead." (Acts 17:30-31)
You must, with sincere heart-belief, confess that Jesus is Lord. He is Lord whether you confess it or not, but it is unto your salvation that you must acknowledge His deity and His ownership (Romans 10:9-10). This confession is the external expression of an internal spirit of complete submission to every aspect of His word and will. As with faith and repentance, confession alone does not save (Matthew 7:21).
Be baptized for the remission of sins "Then Peter said to them, 'Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit.'" (Acts 2:38)
Live a faithful Christian life in the fellowship of Godís people "Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord." (1 Corinthians 15:58) "But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin." (1 John 1:7)
