***Before your sins are washed away or after? ***
What can wash away my sin?
Nothing but the blood of Jesus...
Now go to the next step and conflate water and blood for cleansing of sin. You don’t get the blood till it is applied in the water...Wait, that doesn’t make sense!
In the OT the blood of a sacrifice was mixed with water and SPRINKLED on the people.
Psalm51:
51 Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
2 Wash me throughly from mine iniquity, and cleanse me from my sin.
3 For I acknowledge my transgressions: and my sin is ever before me.
4 Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest.
5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
6 Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.
7 Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.
