If a person has no remorse, expresses no shame, or guilt over their sins, is it your place to correct them? Yes, BUT to correct another’s sins you must first understand your own weaknesses and failures, you have to own those before the Lord, have sought forgiveness, and begun to live a fuller life in Christ. Then the compassion, love and mercy of Christ will govern your experience and desire to help while avoiding both being hypocritical, and judgemental. As the Apostle Paul corrected the Galatians:
“Brethren, if a man is overtaken in any trespass, you who are spiritual restore such a one in a spirit of gentleness, considering yourself lest you also be tempted. Bear one another’s burdens, and so fulfill the law of Christ. For if anyone thinks himself to be something, when he is nothing, he deceives himself. But let each one examine his own work, and then he will have rejoicing in himself alone, and not in another. For each one shall bear his own load.” (Galatians 6:1–5, NKJV)
In Matthew 7:1-5, Christ is addressing the children of God in the 1st century. Judgement in the first century was very different than it is today. Every mature child of God was to judge their own hearts, and in so doing confess their guilt and sin to God, bring a blood sacrifice for the atonement of those sins and to hold themselves accountable to the Law of God both individually and as a people, or a society. The difference today, is the sacrifice for sin has been completed in Christ, the Law has been fulfilled, but the underlying precept of judging our own hearts remains the same. The immediate illustration Christ uses reflect upon the importance of judgement, starting with YOU.
