John 3:11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. 12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
Many call themselves a Christian, but know nothing of the Spiritual things of God for they have never been Spiritually born again nor have the indwelling of the Holy Spirit. There's is a carnal knowledge as they speculate and try to use carnal logic. They only give lip service unto the Lord and these are the ones Jesus will say I never knew you, Matthew 7:21; 25:41.
It did repent God that He created man, Genesis 6:6, but His grace is to all who will repent and turn back to Him. God does not hate what He created, but hates the sin found in them as Proverbs 6:16-19 is what God hates in man with the seventh being an abomination to Him. It's not that God hated Esau, but He hated the sin found in him as even he had a chance to repent and turn back to God.
Luke 14:26 When Jesus said if you do not hate your mother and father and so forth I believe He meant if you hate not the sin found in them you can not be my disciple. Matthew 10:37 says pretty much the same thing as when we love the person (sinful flesh) more than Christ then we are not worthy of Him.
