When Paul told the jailer to believe on the Lord Jesus Christ and thou shalt be saved, what did this belief on Christ cover ? Many places in scripture as with the eunuch when Philip told him "if thou believest with all thy heart, thou mayest, the eunuch's reply was, I believe that Jesus Christ is the Son of God. Apostle Paul's first message after he was converted was Christ was the Son of God, Acts 9:29. When Peter preached to Cornelius part of his message was that through his name ( Christ) whosoever believeth in him shall receive remission of sins, Acts10:43. There were several things in Peters message he covered about Christ, him being anointed of God who went about doing good, and healing all that were oppressed of the devil, Christ being crucified and God raising him the third day. Apostle Paul's message was, This is a faithful saying and worthy of all acceptation, that Christ Jesus came into the world to save sinners 1 Tim 1:15. So if we believe Christ is the Son of God, If we believe God raised him from the dead, If we believe Christ saves sinners. If we believe these things from the heart is these things sufficient for salvation ?
