No one is saying our Lord's words are not true. It's your interpretation of what He's saying that is causing this problem. Which words is He referring to? His words about keeping the commandments? Which words do you claim give life, Jerry?
His words which He spoke to the Jews when He said He is the Christ:
"Then came the Jews round about him, and said unto him, How long dost thou make us to doubt? If thou be the Christ, tell us plainly. Jesus answered them, I told you, and ye believed not: the works that I do in my Father's name, they bear witness of me" (Jn.10:24-25).
The Lord Jesus said He is the Christ and He said that He is the Son of God (Jn.10:36). Those who believed Him were born of God and received spiritual life:
"Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him. By this we know that we love the children of God, when we love God, and keep his commandments. For this is the love of God, that we keep his commandments: and his commandments are not grievous. For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?" (1 Jn.5:1-5).
"And many other signs truly did Jesus in the presence of his disciples, which are not written in this book: But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name" (Jn.20:30-31).
Again, the following statement of the Lord Jesus spoken to those who lived under the law was an "unconditional" statement:
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life" (Jn.6:63).
What the Lord Jesus said there is either true or false. I have told you exactly what His words were which brought spiritual life and so I believe that what He said is true.
On the other hand, you say that His words by themselves were not sufficient to bring spiritual life to those who lived under the law because they couldn't be made alive spiritually apart from works.
