What does justification by faith exclude?

In Romans 3:27, Paul makes it clear that justification by faith excludes all boasting because it is not based on our works but solely on the grace of God through faith in Jesus Christ. This means that no one can claim merit for their salvation, as it is a gift provided by God. Believers are called to boast only in Christ, acknowledging that their justification comes from Him and not from themselves. This teaching leads to a posture of humility and gratitude, recognizing that salvation is an act of grace rather than a reward for personal effort.
