Romans is reminding me about that great divide between being forgiven and being perfect.
I am no longer dominated by my sinful nature but I still have lapses into selfishness or greed or envy or impatience. At what point does the amount of sin outweigh the Spirit living in me and freeing me?
Perhaps I'm too pedantic and literal in my approach?
It's not measured by my mistakes. It's not weighing up my strengths. There's no movable cut-off point or comparative marking.
Just yes or no to this question.
Does Jesus live here? (~points to chest~)
Do I see actions in my life that are prompted by Jesus? Do I listen to him as he guides me, teaches me and pushes me from within? Do I spend time with him? Do I take every opportunity to know him and to nurture his spirit in me?
Jesus can only live in me if I give him space in my life.
But you are not controlled by your sinful nature. You are controlled by the Spirit if you have the Spirit of God living in you. (And remember that those who do not have the Spirit of Christ living in them do not belong to him at all.)
