“Telling someone to “go & sin no more” is a lot different than following them around and trying to prevent them from sinning more”
In these two examples, Jesus tells people to stop sinning.
First, the “Woman caught in Adultery.”
“He who is without sin among you, let him be the first to throw a stone at her.” Again He stooped down and wrote on the ground. When they heard it, they began to go out one by one, beginning with the older ones, and He was left alone, and the woman, where she was, in the center of the court. Straightening up, Jesus said to her, “Woman, where are they? Did no one condemn you?” She said, “No one, Lord.” And Jesus said, “I do not condemn you, either. Go. From now on sin no more.” John 8: 7-11
Secondly, The man who was waiting by the sheep gate pool who had been sick for 38 years.
“Afterward Jesus found him in the temple and said to him, “Behold, you have become well; do not sin anymore, so that nothing worse happens to you.” John 5:14
Two questions:
1. Do we like Jesus have the authority to tell others to “go and sin no more?”
2. Should we?

Question, Did they sin ever again?
The question isn’t if they ever sinned again, I’m sure they did. The question is did they ever into a practice of sinning? Who knows?
But that’s what Jesus was telling them no to do. “No one who abides in him keeps on sinning” 1 John 3:1-10
I think we need to be careful of taking any one verse or one example out of the Bible and making it a hard and fast rule about EVERYTHING. In the case of the woman caught in adultery, I assume that it was pretty clear to her that she was majorly screwing up – that she KNEW she was in sin. He told her to go and sin no more probably because she didn’t know she could get up from where she was presently languishing. But not everyone was in the same situation. Zachias for instance, Jesus didn’t tell him to go and sin no more – Jesus didn’t even address him as a sinner – Zachias was in an altogether different place than that woman in reference to his own sin as he up and volunteered, “I’m going to give back 4 times what I’ve taken..” Some people are in other places – some are so estranged from God’s spirit that they don’t even know they are sinning, and can’t understand why someone else thinks what they are doing is sin.
But that’s only one aspect of this – because before we think we can go tell someone to “go and sin no more” I think we need to know we can impart the same grace to them that Jesus’s words imparted to this woman. So the question becomes – can we also say like Jesus, “Little Girl, I say to you, arise?” Because if we don’t have the same grace to raise the dead like Jesus did, then we might not have as much authority to set someone free from sin. I think both are possible – we CAN have the authority to set someone free from sin, and we can have the authority to raise the dead with a word. But ARE we currently walking in such authority? If not, our words may only serve to put a heavier burden on the back of the ones hearing us.
Heather we do need to be careful about taking singe verses out of their context and making any unwarranted conclusions, but single verses removed from their context appropriately do not pose any issues.
Using what Jesus “didn’t say” is a classic argument from silence. We can make no theological conclusion or application based on what wasn’t said.
Excellent last part about placing burdens on others and applying the ministry of both sides of the fence. If we are going to tell others to “sin no more,” we should be just as poised to set them free.
The scripture is simply a wonderful tool for the Holy Spirit to use. In our well educated western mindset we have come to rely on our intellect to provide us the “answers”. We dissect and pour over the scriptures with our minds, in search of the solutions. Jesus said as much in John chapter 5. What we need to know, in every one of life’s circumstances is: Jesus what do you want to do here? Jesus set up the examples for us, “I only say what I hear the Father say, and do what I see Him do.”
Not the we have already attained, but we work to enter His rest.
the 2 questions are really 1.
Jesus is still telling women & men today to be done with their sinning. Not for the sins of which they may be unaware, but for those of which He has made us aware. If it seems like Hes asking too much, by this we know that we still have need to enter into His Salvation; His Life.
