Is It "Water Salvation" To Teach A Sinner Has To Be Baptized To Be Saved?

Regarding baptism, certainly the power is not in the water; it is in the blood/death of Christ.The question is → When does the blood of Christ wash away sins, before or after (at) water baptism?· II Kings 5:14 - Naaman “dipped himself seven times in Jordan” and was cleansed of his leprosy. Was the cleansing power in the water? No, the power was with God. But when was he cleansed of his leprosy, before or after he dipped seven times in the water?· Numbers 21:4-9 – The Israelites who looked upon a brass serpent set on a pole were healed of their snake bites. Was the healing power in the brass? No, the power was with God. But when were they healed of the poison, before or after they looked upon the serpent?It is the same with regard to water baptism and the washing away of sins. Acts 22:16 ("arise, and be baptized, and wash away thy sins") clearly teaches that a person’s sins are not washed away (by the blood of Christ) until said person is baptized.
