Apparently, he is using the words of Jesus "go and sin no more" in John 8:11 to teach sinless perfection. Jesus was telling the woman to go and leave her life of sin, namely, she had been practicing adultery. Also, Jesus cannot compromise his perfect holy standard, so of course He is not going to tell her, "go and just sin a little bit." I don't believe that Jesus truly expected the woman to live a sinless, without fault or defect, flawless, absolute perfect life 100% of the time after that and those who believe they live a sinless, perfect life 100% of the time (exactly as Jesus lived) are suffering from a terminal case of self righteousness. (1 John 1:8-10)
Yes Jesus did not expect her to be sinless.
If he did along with those he met whilst on the earth then he would have no need to die. He would have just said "Stop sinning full stop and you will be ok"
I think this whole scenario is twofold.
Those who bought this woman were trying to trap Jesus and in fact under the law Jesus could not condemn her as there were no witnesses or accusers that would step forward and say they caught her in the act.
So Jesus could not condemn her but he turned it round and used it against the Pharisees and the scribes.
John 8:7-12
7 So when they continued asking Him, He raised Himself up and said to them, “He who is without sin among you, let him throw a stone at her first.” 8 And again He stooped down and wrote on the ground. 9 Then those who heard it, being convicted by their conscience, went out one by one, beginning with the oldest even to the last. And Jesus was left alone, and the woman standing in the midst. 10 When Jesus had raised Himself up and saw no one but the woman, He said to her, “Woman, where are those accusers of yours? Has no one condemned you?”
11 She said, “No one, Lord.”
And Jesus said to her, “Neither do I condemn you; go and sin no more.”
12 Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.”
We see "Any you sinless?
What a question to ask, how could anyone say yes? They cannot.
The accusers have gone and can no longer condemn her.
That's why Jesus could not condemn her because under the law two witnesses were needed from sentance to be passed.
I believe Jesus knew she was guilty and as God could have pronounced that.
Yet he says lovingly "I don't codemn you, now go live differently"
He didn't say "Until you stop sinning you are condemned"
Go now live differently?
12 Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.”
I reckon this woman having been spared death and meeting Jesus would have seen the light of the world and want to walk in the light and not the darkness.
Sinless "NO"
Wanting to sin less "YES"
