God cares about our sin. Not because He wants to infringe on free will or control all the things we do in our everyday lives. God cares about our sin because He knows that the deeper we dive into sin, the further we stray from a relationship with Him. This holy nature of God is something that Jesus followers should seek, not as a desire to be better than others but as a desire, a real longing to grow closer to our Heavenly Father.
