What does the Bible say about true and false faith?

The distinction between true and false faith is grounded in Christ's teachings, particularly in the Sermon on the Mount. In Matthew 7:21-23, Jesus warns that not everyone who claims Him as Lord will enter the Kingdom of Heaven, but only those who do the will of His Father. This shows that authentic faith is demonstrated through obedience to God's commands, rather than through mere verbal profession. True faith produces good works because it is rooted in the grace of God, which transforms and empowers believers to live righteously.
