How do we know true saving faith is real?

The assurance of true saving faith can be found in its characteristics, as described in Romans 4. For example, true saving faith believes God, looks beyond difficulties, and does not stagger at His promises (Romans 4:20). It is fully persuaded that God is able to perform what He has promised (Romans 4:21). This faith glorifies God and takes Christ as the sole foundation for justification. When one fully trusts in the risen Christ and acknowledges Him as their savior, they can be confident that their faith is genuine and true saving faith, as it aligns with Scripture.
