That's an easy question.Could you tell me how much water saves you?
one drop? one Gallon? an ocean full?
You can't answer this, no one ever has.
I can tell you just one drop of blood can save your soul.
Jesus paid the price, all one needs is to believe, do you?
Once again, the Holy Bible never tells us Water baptism saves us.
No, water does not save you; however by that same line of literal reasoning, blood will not save anyone either.
It is the waters of baptism unto repentance which can save you. Likewise, it is the blood of Christ being spilt on our behalf, which saves us from physical death, and allows for us to be saved from spiritual death as well.
But then, you likewise believe in ordinances done only by someone with the authority to do them, has the power to save people as well; so I don't understand your objection.
