Romans 6:1-14 – Who will reign

Concentrating on verses 11-14, we see that while sin has been defeated by Jesus and while he died for our sin, yet sin is powerful and wages war on our souls with the aim of reigning in our lives. we seek to ask whether we are responsible for fighting sin, or it is God on our behalf? Do we do it in cooperation with him? Is it something we can even ever overcome? Will we get better at defeating sin?
