I often opine that Jesus never asks us to accomplish anything that cannot be done with the help of the Holy Spirit. So his admonition in Matthew 5:48 must be a goal that can be reached. While it is true that none of us will ever be perfect in this life, the high and beautiful standards Jesus set forth in the Sermon on the Mount remain the goals toward which every follower of Christ is invited to aim. By God’s grace and through the quiet, steady work of the Holy Spirit, we can grow in those qualities day by day. Jesus Himself said, “But you are to be perfect, even as your Father in heaven is perfect” (Matthew 5:48, NLT). This is not a harsh demand meant to crush us; it is a loving invitation to become more like the Father who already loves us completely.
Many thoughtful believers quietly wonder, “How good must I be to stay saved? I know I am a sinner. Nothing I do will ever be perfect. What can I do to be saved and to keep on walking with God?” Of course, this represents wrong thinking. The answer is that our own efforts were never the foundation of our salvation. Instead, we receive the perfect righteousness that God Himself has provided through the atoning, substitutionary death of Jesus Christ. Scripture tells us, “For God made Christ, who never sinned, to be the offering for our sin, so that we could be made right with God through Christ” (2 Corinthians 5:21, NLT). Only the Lord is perfect, and in His kindness He works to perfect those who trust in Him.
Here are three biblical truths that can help us hold this truth with both humility and hope.
First, we are sinners, and there is no need to deny it. Sin is an offense against a holy God, and He cannot simply overlook it. The Old Testament already called God’s people to reflect His character: “You must be holy because I, the LORD your God, am holy” (Leviticus 19:2, NLT). Sin had to be dealt with according to His just standards. That is why the Father sent the Son to die for us. Jesus bore the full penalty of our sins, and through His one sacrifice He forever settled every claim of divine justice against those who believe. As the writer of Hebrews explains, “For by that one offering he forever made perfect those who are being made holy” (Hebrews 10:14, NLT). By trusting Jesus as our Savior that single step of faith places us firmly under the covering of His finished work.
Second, from the very moment we believe, God begins a lifelong work of perfecting us. We receive a perfect standing before Him, yet our daily lives still show how far we have to grow. The apostle Paul helps us understand this tension. He writes, “I don’t mean to say that I have already achieved these things or that I have already reached perfection. But I press on to possess that perfection for which Christ Jesus first possessed me” (Philippians 3:12, NLT). Paul is speaking of absolute maturity—the full likeness of Christ. In the very next breath he adds, “No, dear brothers and sisters, I have not achieved it, but I focus on this one thing: Forgetting the past and looking forward to what lies ahead, I press on to reach the end of the race and receive the heavenly prize for which God, through Christ Jesus, is calling us. Let all who are spiritually mature agree on these things… But we must hold on to the progress we have already made” (Philippians 3:13-16, NLT).
Here “perfect” or “mature” points to stages of growth. Even as a seasoned apostle, Paul knew he had not arrived at sinless perfection. He did not make excuses for failure, yet he also rested in the fact that every past guilt had already been covered by the cross. The penalty is removed; the daily process of becoming holy continues. God has graciously provided a way for cleansing and restored fellowship whenever we stumble: “If we claim we have no sin, we are only fooling ourselves and not living in the truth. But if we confess our sins to him, he is faithful and just to forgive us our sins and to cleanse us from all wickedness” (1 John 1:8-9, NLT).
Third, our ultimate perfection—what the Bible calls glorification—will arrive the moment we see Jesus face to face. John writes with tender assurance, “See how very much our Father loves us, for he calls us his children, and that is what we are! … Dear friends, we are already God’s children, but he has not yet shown us what we will be like when Christ appears. But we do know that we will be like him, for we will see him as he really is. And all who have this eager expectation will keep themselves pure, just as he is pure” (1 John 3:1-3, NLT). Until that day we never experience complete freedom from the presence of sin. Yet when Christ returns, or when we go to be with Him, we will be presented pure and complete—filled with love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control, wisdom, humility, and joyful obedience.
The psalmist already celebrated the perfection of God’s ways: “God’s way is perfect. All the LORD’s promises prove true. He is a shield for all who look to him for protection” (Psalm 18:30, NLT). What God begins in the new birth, He faithfully continues until the work is finished. So Paul could say with confidence, “And I am certain that God, who began the good work within you, will continue his work until it is finally finished on the day when Christ Jesus returns” (Philippians 1:6, NLT). The same God who chose us also calls us, justifies us, and will one day glorify us (Romans 8:28-30, NLT). He never abandons any of His children.
So we keep aiming at Christlike character—not out of anxious striving, but out of grateful love. We receive His perfect righteousness as a gift, we walk daily in the Spirit’s gentle power, and we look forward with hope to the day when the work will be complete. In the meantime, the Father who is perfect is patiently, lovingly shaping us into the likeness of His Son.
Blessings on you and yours,
