Romans 6:5-6

For since we are permanently grafted into him to experience a death like his, then we are permanently grafted into him to experience a resurrection like his and the new life that it imparts. Could it be any clearer that our former identity is now and forever deprived of its power? For we were co-crucified with him to dismantle the stronghold of sin within us, so that we would not continue to live one moment longer submitted to sin’s power.
