What does the Bible say about believing in Jesus for salvation?

The Bible consistently underscores the necessity of faith in Christ for salvation. In Acts 16:31, Paul tells the Philippian jailer to 'believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.' This belief is not mere acknowledgment of His existence but a deep trust in His redemptive work. Similarly, in John 3:15, the scriptures declare, 'Whosoever believeth in Him shall not perish, but have eternal life.' This shows that salvation is granted to those who have faith in Christ's ability to save, emphasizing the relational trust that believers are called to have in Him.
