As we proclaim a message of God's unconditional love and free grace apart from the works of the law and commandments, those bound by legalistic teaching will ask us whether behavior matters. It's hard for them to grasp wanting to do what is right and good apart from rules and regulations. In the same way that God has shown forgiveness and love to us in this New Covenant, as new creations in Christ, we are now empowered to do the same. It's because we're branches, engrafted into the tree of life, bearing his fruit apart from law.
