You mention TWO baptisms here and God says there is only ONE in Eph 4. I wuold stick my faith in ONE BAPTISM. As I would choose to believe God's word above your understanding. Sorry ji. Either you knwo or God knows. God says one baptism you mention two... So I will believe there is only ONE!
And when Jesus said in John 3 .... Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
Please do not think this is h2O (water as n drinking water or river water) it is the LIVING WATER of the WORD. It is the water Jesus mention a few times in the Bible. It is the Word of God WATER that a person should be born of, and also the Holy Spirit of God. And we know how the process work from the WATER and the SPIRIT.
So, my friend you are totally mislead by something.... There is one baptism, ONE LIVING WATER GIVER and ONE SPIRIT....
