Not reading those as the same.
The quote is trite.
The verses are rich in meaning.
If these verses are the origin of the quote it is no wonder there is such a shipwreck being made of the church in America.
We all sin and one sin is no worse than any other.
I have only seen 'Let go and let God' in 12 step rooms. It's in a frame and on the wall sometimes. Trite maybe, but it's something a newcomer who was never exposed to the Bible can remember when they feel like giving up. See, these folks have lost God or more likely, never knew Him. In meetings, we WITNESS the power of God in our lives.
Alcoholics, drug addicts, compulsive over-eaters, gamblers, sex addicts, etc all have a God sized hole that is killing them and their souls. We don't send people away to seek help - we're the last house on the block. Without us, it's jails, institutions and death. We've 'been there, done that' and can communicate like no ordained clergy can.
We do the real work of repentance and regeneration. For me, I came to know God and sanity through the 12 steps - not any church.
Luke 6:47 Whoever comes to Me, and hears My sayings and does them, I will show you whom he is like: 48 He is like a man building a house, who dug deep and laid the foundation on the rock. And when the flood arose, the stream beat vehemently against that house, and could not shake it, for it was founded on the rock. 49 But he who heard and did nothing is like a man who built a house on the earth without a foundation, against which the stream beat vehemently; and immediately it fell. And the ruin of that house was great.
