Unless you admit that you are sick and in need of Him you will always fail in your endeavour to overcome sin.
Jesus said apart from Him you can do nothing.
Only the sick need the doctor!
New American Standard Bible (NASB)
5 I am the vine, you are the branches; he who abides in Me and I in him, he (A)bears much fruit, for apart from Me you can do nothing.
New Living Translation (NLT)
31 Jesus answered them, “Healthy people don’t need a doctor—sick people do. 32 I have come to call not those who think they are righteous, but those who know they are sinners and need to repent.”
