And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years, Genesis 6:3. Could it be that whether or not a word is capitalized has any meaning in our King James Bible? Why would the LORD, who is Jehovah God ever have his spirit designated by lower case "s"? Because Jesus is the Lord. Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Ghost, I Corinthians 12:3.
When we read the Gospels, we see the spirit of Jesus Christ still striving with man. When I preach from the pulpit, I still see the spirit of Jesus Christ striving with man. He warned the world in Genesis 6:3 that he would not always strive with man, but thank God he still is. The day will come when he ceases to do so.
1. And immediately when Jesus perceived in his spirit that they so reasoned within themselves, he said unto them, Why reason ye these things in your hearts? Mark 2:8.
2. And he sighed deeply in his spirit, and saith, Why doth this generation seek after a sign? verily I say unto you, There shall no sign be given unto this generation, Mark 8:12.
3. And the child grew, and waxed strong in spirit, filled with wisdom: and the grace of God was upon him, Luke 2:40.
4. In that hour Jesus rejoiced in spirit, and said, I thank thee, O Father, Lord of heaven and earth, that thou hast hid these things from the wise and prudent, and hast revealed them unto babes: even so, Father; for so it seemed good in thy sight, Luke 10:21.
5. And when Jesus had cried with a loud voice, he said, Father, into thy hands I commend my spirit: and having said thus, he gave up the ghost, Luke 23:46.
6. When Jesus therefore saw her weeping, and the Jews also weeping which came with her, he groaned in the spirit, and was troubled, John 11:33.
7. When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me, John 13:21.
By leaving Genesis 6:3 alone, the Bible believer can make one of the strongest cases possible that Jesus is the Lord. The spirit of which he spoke in Genesis 6:3 is the same spirit that he yielded back to the Father in Luke 23:46. It is the same spirit with which he strove with man in the Gospels. There is a lot that can be learned form having a perfect text. There are still brethren out there who think that a King James Bible can be perfect even with varying texts. They are wrong. Only one text of the King James Bible is 100% accurate. Cambridge doesn't print it any more. Local Church Bible Publishers doesn't publish it any more. The Schofield Reference Bible is a joke. Maybe you should look into the issue.
