Your whole argument rests on this claim: that nothing is required from the person at all, either to enter salvation or to remain in it. That idea does not come from Jesus. It comes from reading later writings in a way that cancels His direct words. That is a serious mistake.
First, Jesus never taught that obedience is optional or irrelevant. He tied salvation to obedience again and again. He did not say obedience earns salvation, but He did say obedience is required to enter and remain in life.
Jesus said, “If you want to enter into life, keep the commandments” (
Matthew 19:17, NKJV). He did not say, “You cannot keep them,” nor did He say, “They no longer matter.” He said keep them.
Jesus said, “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven” (
Matthew 7:21, NKJV). Calling Him Savior is not enough. Doing the Father’s will matters.
Jesus said, “If you love Me, keep My commandments” (
John 14:15, NKJV). Love without obedience is rejected by Jesus Himself.
Jesus also warned believers, not unbelievers, about being cut off. “Every branch in Me that does not bear fruit He takes away” and “If anyone does not abide in Me, he is cast out as a branch and is withered” (
John 15:2,
6, NKJV). That is not imaginary. That is a warning about losing life by refusing to remain obedient.
Now about the New Covenant. You say the law written on the heart is not the Ten Commandments. But Scripture never says God erased His moral law. The Ten Commandments are not sacrifices. They never were. They are simple commands about loving God and loving others. Jesus confirmed this when He said all the law hangs on loving God and loving your neighbor (
Matthew 22:37–40, NKJV). He did not replace them. He revealed their true depth.
The book of Hebrews is talking about priesthood, sacrifices, and the system that dealt with sin through offerings. That is what changed. Jesus is the final sacrifice. That part is finished. But Hebrews never says God removed His moral commands or that obedience no longer matters. Saying “the law made nothing perfect” is not the same as saying “the law is gone.” The law shows what sin is. Jesus cleanses us so we can walk in obedience, not so we can ignore it.
Jesus Himself explained the New Covenant life. “Blessed are the pure in heart, for they shall see God” (
Matthew 5:8, NKJV). “If you do not forgive men their trespasses, neither will your Father forgive your trespasses” (
Matthew 6:15, NKJV). Those are salvation warnings, not suggestions.
Grace is real. Mercy is real. Forgiveness is real. But grace does not remove obedience. Grace teaches obedience. Jesus never said a person is saved with no conditions afterward. He said, “He who endures to the end shall be saved” (
Matthew 24:13, NKJV).
This teaching that nothing is required at all is dangerous. It gives false peace while leading people away from the fear of God. Jesus warned that many will think they are safe and will hear, “I never knew you; depart from Me, you who practice lawlessness” (
Matthew 7:23, NKJV). Lawlessness means living without obedience.
This is a warning given in love. Do not cancel the words of Jesus to protect a system. Do not tell people obedience does not matter when Christ Himself says it does. Salvation is a gift, but it is a living gift. It can be rejected by disobedience, neglect, and refusing to abide in Him.
Jesus saves. Jesus cleanses. Jesus gives mercy. But Jesus also commands, warns, and judges by His own words. And He said clearly, “If anyone hears My words and does not keep them, I do not judge him; for the word that I have spoken will judge him in the last day” (
John 12:47–48, NKJV).
That should make anyone stop and and thing twice before speaking against what Jesus the son of God preached to the world.
