What does the Bible say about the importance of faith in Jesus?

The importance of faith in Jesus is foundational in the Christian faith as it leads to salvation and the ability to become a child of God. John 1:12 states, 'But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name.' This signifies that faith is not just a mere acknowledgment but is an active receiving and believing in Jesus Christ. Furthermore, faith connects believers to the life-giving grace of God, as Ephesians 2:8 explains that by grace are ye saved through faith, highlighting that it is not of ourselves but the gift of God.
