But for my Master

     But for my master, I do the bidding of God.  Sometimes I worry that my master is the devil.  I cannot banish sin completely from my life. I want to do what is good but sin always seems to hang around.  I do things, I say things and I think of things that are ungodly when I am in the privacy of my own consciousness.  I am depraved.  Am I destined for hell and do I believe in a false hope of salvation? I thought I was transformed by my conversion but I have drifted back to some old habits.  Why does not this transformation take hold and become permanent? Why does the Holy Spirit come and go?  I cannot find the answer even though wisdom has granted me her insights.  I vacillate between the darkness and the light. God, please help me overcome this darkness. I see so much good in this world but I wonder if these good men also fight against the darkness as I do?   Am I predestined for eternal damnation? Are some men predestined for eternal salvation? I cannot do the good that I want.  Something keeps holding me back.  Who is my master? Jesus is. Even though I fight against the devil, can I ever banish him completely from my life?  Is good works the answer?
