Romans 6:4-6 (NLT)
4 For we died and were buried with Christ by baptism. And just as Christ was raised from the dead by the glorious power of the Father, now we also may live new lives.
5 Since we have been united with him in his death, we will also be raised to life as he was. 6 We know that our old sinful selves were crucified with Christ so that sin might lose its power in our lives. We are no longer slaves to sin.

We are no longer slaves to sin if we choose not to be – theoretically; well, we can move away from it and repent when we screw up, go at life again renewed. The key thing is that our intentions must have changed to one of wanting to please God for who he is, not what he’ll do for us. It’s not that we won’t sin, it’s that we’re earnestly striving to not sin – well at least until we say screw it (most sin is intentional) and sin again. If it’s maddening for us, I wonder how God feels about it. Yet His forgiveness is endless since we are united with him through Christ’s death for these sins.

Job 37:5 (NIV)
5 God’s voice thunders in marvelous ways; he does great things beyond our understanding.

John 12:25-28 (NLT)
25 “Those who love their life in this world will lose it. Those who care nothing for their life in this world will keep it for eternity. 26 Anyone who wants to serve me must follow me, because my servants must be where I am. And the Father will honor anyone who serves me.
27 “Now my soul is deeply troubled. Should I pray, ‘Father, save me from this hour’? But this is the very reason I came! 28 Father, bring glory to your name.”
Then a voice spoke from heaven, saying, “I have already brought glory to my name, and I will do so again.”

We’ll never be perfect until we die, so we’ll sin in this life. When we leave this life though we’ll be perfect with God or perfect without him. One is an eternity of love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control all in the presence of our pure loving God we’ll never fully understand while here in this life. The other is perfectly absent of all of those – none, nothing like that, the opposite.

John 12:36 (NLT)
36 “Put your trust in the light while there is still time; then you will become children of the light.”

Psalm 51:1-2 (NLT)
1 Have mercy on me, O God,
because of your unfailing love.
Because of your great compassion,
blot out the stain of my sins.
2 Wash me clean from my guilt.
Purify me from my sin.
