.... The faith God requires of us for salvation is belief in what the Bible says about who Jesus is and what He accomplished and fully trusting in Jesus for that salvation (Acts 16:31). Biblical faith is always accompanied by repentance (Matthew 21:32; Mark 1:15).
The biblical definition of faith does not apply only to salvation. It is equally applicable to the rest of the Christian life. We are to believe what the Bible says, and we are to obey it. We are to believe the promises of God, and we are to live accordingly. We are to agree with the truth of God’s Word, and we are to allow ourselves to be transformed by it (Romans 12:2).
Why is this definition of faith so important? Why must trust accompany agreeing with facts? Because “without faith, it is impossible to please God” (Hebrews 11:6). Without faith, we cannot be saved (John 3:16). Without faith, the Christian life cannot be what God intends it to be (John 10:10).
