It is true that, “Lord, on my own, I cannot do the right thing nor stop sinning.”
“I Am The Vine, you are the branches. He who remains in Me, and I in him, bears much fruit. For without Me, you can do nothing.” John 15:5
Don’t waste many years, as is so easy to do, trying to do the impossible.
Living, as He desires for you, is only done supernaturally with His help.
His help is in your being one with Him.
He provides Himself to bear fruit and overcome in and with you.
Even regarding your faith.
Remember that, “… if you do not believe, He remains believing: He cannot deny Himself.” 2 Timothy 2:13
Your spirit, that is one with His Spirit, relies on Him always believing, and shares Him in His faith.
“… the one who is joined to the Lord is one spirit with Him.” 1 Corinthians 6:17
The Vine shares Himself in His faith with and through your branch.
It is absolute truth, that apart from Him, you can do nothing.
But in Him, you “can do all things through Christ Who strengthens” you. Philippians 4:13
