All I'm saying is that the circumcision made without hands, the circumcision of Christ, biblically, happens at the time of baptism (see Colossians 2:11-12) in water (see 1 Peter 3:20-21 (kjv)). I would say that God is the One who performs every baptism that brings the result of the promised Holy Ghost; with man as a mediator of the sacrament.
1Pe 3:20, Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
1Pe 3:21, The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
At the very least, the Holy Ghost is absolutely promised to all those who receive this ordinance.
Why wouldn't you just take the plunge and remove all doubt as to whether you have the Holy Ghost? You receive baptism in Jesus' Name, you absolutely have Him!
