To say that when we sin, it is not all of us that sins, but only our flesh, reeks of gnosticism.
Gnosticism teaches that what we do in the flesh doesn't matter because the real "us" isn't sinning when we sin sins of the flesh.
Set aside Gnosticism for a moment, I get your point, though that's not really what this is about. That God created everything might remind you of Hinduism, and Brahma, God is not an hindu God.
But this is what Scripture says, plainly, in Romans 7. Therefore it is no longer I that sin, but sin that lives in me.
Identifying yourself - the spirit child of God - with the man of sin is, in my estimation, a mistake, and, I think, generally causes people to ascribe things that aren't true.
I believe that when I am not living in an active reliance on God, walking in the Spirit, experiencing the fruit of the Spirit, well, I may be walking according to the flesh, which may even have a certain resemblence to the mind of Christ, though putting it to the test proves whether the mind of the flesh or the mind of Christ is actually ruling the body.
God declares that we have been created - our new creation, the new man - we have been created in God's pattern, in righteousness and true holiness. I believe that to be true.
God teaches us that we are new creations, that all is now new, and now all is from God. I believe that to be true.
And God teaches is that sin is no longer what I am doing, rather, when there is sin, I am not the one truly committing it, rather, sin still lives in me, specifically in my body of flesh, corrupted by sin.
So I am not condemned by my sin. I have no more stain of sin, Hallelujah!!!!! No More Stain!!!! Thank you Jesus!!!!!!!!
And at anytime that I do sin, I can be reminded, Jesus has set me free, and sanctification is increasing as He increases in me. As I gaze into Him with the purity in innocence He's given to me. As He shines into my heart with no impediment.
At anytime I do sin, I believe it is because my faith in God has faltered, my eyes got pulled onto the waves, instead of simply walking in obedience regardless of how things look. The moment we think 'this may not work out right' and start entertaining other avenues, leaving a total trust, starting to consider for ourselves how to make this work out right, in that moment we've started allowing that old flesh mind to run thoughts through the brain.
And if we don't recognize that, and take those thoughts captive, we may find ourselves in sin. The flesh mind, if it's not going overboard, can sound just like us, in fact, that used to be us.
Renewing the mind is to learn about God, about Jesus, and as we come to understand Him better, to know Him more, we see more clearly where we don't match up, and we put that off, to put Him on.
Walking in the Spirit is what our spirit by virtue of it's nature does. If we are not experiencing in our lives the fruit of the Spirit, then we are not walking in the Spirit. The fruit of the Spirit is love, joy, peace, let's start there.
There is something that I know that whenever I hold this in mind, I am flooded immediately with love, and joy, and peace, even when circumstances are very difficult, painful, confusing. But that love and joy and peace is constant, as I hold this truth in mind. I am reconciled to God.
Let's add self-control to our list.
When I have in mind, in my heart, that truth, I am reconciled to God, and as I believe it - be it to you according to your faith - as I believe in His reconciliation, my heart, my mind, spring open wide to Him. God has redeemed me, and I am His. He made me because He wants me, and sin doesn't change that, He fixed that. Because He wants what He wants, and He wants you, and me, and all of us who will have Him.
In my faith that God has returned me to Him, and that He is restoring me to His original design, is my salvation, and also my access into the grace in which I stand. The faith that Jesus' death and resurrection are sufficient, and I am reconciled to God.
And along with the love and joy and peace that floods into me, there is also that self-control, as the Spirit controls, simply by leading us through a much better life.
Sorry for the length . . . I kind of 'launched' there. But I do think this is of paramount importance to understand to live the most abundant life we can.
Much love!
