Yes sir, I have preached Matthew 7:22-23 many many times.The verse I quoted from John 9:31 applies to me too.
John is addressing those who do not walk in the light, in verses 6, 8, and 10.
They cannot say they have fellowship with God or that they have no sin, or that they have never sinned.
From 1 John 2:3-6, we also know those who walk in darkness cannot say they know God.
I do believe them.
I also know who they are written about.
Sinners cannot walk in the light, because the light is God; and there is no sin in God.
Those walking in God, can say they have no sin.
If one sins, they are not free from death or the sin's consequences.
If we do as Paul taught in Rom 6:6, we can destroy the flesh.
If we do as Paul taught in Rom 6:3-4, we can crucify the old man and be raised from the grave, with Christ, to walk in newness of life.
Gal 5:24..."And they that are Christ's have crucified the flesh with the affections and lusts."
You've misinterpreted Rom. 7.
As there is no sin in Christ, or in His Father, no sinner is in Christ.
Better read Matt 7:22-23..."Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity."
It is amazing to me that YOU would point those Scriptures toward me as YOU by your own admission are sinless. YOU have just committed the sin of self-righteousness. That is exactly the CONTEXT of the Scriptures you posted.
The CONTEXT is In Matthew 7:15-20 where Jesus warned about the danger of false prophets that lead many astray. They are dangerous because if you believe their lies, they will change you internally. They can affect who you really are and your eternal destiny. They come and deceive by presenting falsehood as the truth. Jesus gave warning about them because they do not appear as the wolves they really are, but as friends of the flock. They come wearing sheep’s clothing, the garments of the shepherd.
If you will read the Sermon on the Mt., you will understand that throughout it, Jesus was presenting the nature of true righteousness as compared with the self righteousness seen in the Scribes and Pharisees of that time.
The hypocrisy of self righteousness is seen in its condemnation of others because they do not do what they do, think as they do yet their own sin is greater.
Think about that my friend.
