If I may be so bold.
You are stuck in Romans 7 situation. Which in itself is not a bad thing, it shows you are being taught by Christ. After Romans 7 has had its complete work in you, you will come to the end of yourself (your self effort). Than as Christ reveals His salvation in you, you will cry out like Paul did “oh wretched man that I am who will deliver me from the body of this death”. Paul, as all Christians must be, was brought to the end of Himself, where he had no strength whatsoever to save or change himself, so he throw himself into the arms of the Lord, that Jesus himself would do for him what he could not do for himself. It is when a believer see that when “Christ died they died.” This is the secret of living a victorious Christian life. To learn to “reckon yourself died” but this cannot be done correctly, till it is seen as a truth “inwardly.” Pray that God Himself would open these truths to you by experience. For once this is learned your Christianity will take on a whole new life. You will be living out from the new creation. A permanent smile and a joy in your heart, that no one, or nothing can take away. But this lesson is hard learned, and can only be learned by experience. But it is for all Christians, all that are willing to pay the price. What is that price. Everything you have, all of “self”. I know these words are cryptic. But take them to the Lord and ask Him if there’s any truth in them. Prayers for you.
Much love in Christ, Not me
