Why is it then brother I am accused of sinning of something fulfilled? And why is it that the law is so focused, instead of doing what's right in the Spirit?
Our Father knows what's in our hearts. But to truly learn to obey God's law in the OT is to obey Jesus. There is a verse somewhere, Jesus says, if you obey My commandments you abide in My love, just as I obeyed my Father's commandments and abide His love. Jesus kept the Father's words, we couldn't. But if we obey Jesus's words then we abide in His love.
Teach righteous deeds through the Spirit, not the law. Rather than teach that obedience through the law, teach obedience through the Spirit.
