Matthew 7:21-23 is a stark warning from Jesus about self-deception and the nature of true faith, concluding His Sermon on the Mount. The passage declares that merely professing belief or engaging in religious activities is insufficient for entering the Kingdom of Heaven.
Jesus states, "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven". On Judgment Day, many will point to their impressive works as evidence of their devotion. However, Jesus will declare to them the terrifying words: "I never knew you; depart from me, you who practice lawlessness".
The core issue is not a lack of visible works, but a lack of genuine, personal relationship and heartfelt obedience. True faith is evidenced by a life of obedience, which is an outflow of an authentic relationship with God, not a means to earn salvation. The "will of the Father" involves trusting in Christ alone for salvation and producing the "fruit" of a transformed life, a life that reflects God's love and righteousness, rather than relying on one's own efforts or religious performance. This passage emphasizes that true discipleship requires total commitment and a life that aligns with God's commands and character.
