God doesn’t just want to fix your habits, he wants to heal your heart.
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.” Matthew 5:17-20 NIV
“You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.” Matthew 5:27-28 NIV
“It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce.’ But I tell you that anyone who divorces his wife, except for sexual immorality, makes her the victim of adultery, and anyone who marries a divorced woman commits adultery.” Matthew 5:31-32 NIV
“You stubborn people! You are heathen at heart and deaf to the truth. Must you forever resist the Holy Spirit? That’s what your ancestors did, and so do you! Name one prophet your ancestors didn’t persecute! They even killed the ones who predicted the coming of the Righteous One—the Messiah whom you betrayed and murdered.”
Acts 7:51-52 NLT
