"Believe on the Lord Jesus Christ and you will be saved" (Acts 16:31). The Bible is clear to answer the question. Base your salvation on the written word of God in your Bible. Trust the promise of God to save you as a believer in the Lord Jesus Christ.
Believe on the Lord Jesus Christ and be saved through the gospel. The gospel teaches Christ died for our sins. He is risen from the dead as our living Savior and Lord (1 Corinthians 15:1-4). Believers confess that Jesus Christ is Lord (Romans 10:9).
Believe and be completely saved. God promises that Christ does in you what you could never do for yourself (Hebrews 13:20-21). God will "make you complete in every good work to do His will, working in you what is well pleasing in His sight, through Jesus Christ, to whom be glory forever and ever. Amen" (vs. 21). Therefore, to be saved is to please God through Christ. Your relationship with God in Christ is forever.
Believe and be saved by grace through faith in Christ. Jesus is the fulness of God's grace (John 1:16). The grace of Christ saves you through faith in Christ. Grace in Christ is the gift of God (Ephesians 2:8-9). Grace is God's unmerited favor for sinners. You are saved by God's grace in Christ.
God saves us "that we who first trusted in Christ should be to the praise of His glory" (Ephesians 1:12). To God alone be the glory, "to the praise of the glory of His grace by which He made us accepted in the Beloved" (Ephesians 1:6).
