Let's dissect I Peter 3:21. Why are there so many contradictions to other Scriptures in just one verse?

I Peter 3:20 says in part "...eight souls were SAVED BY WATER.

I Peter 3:21 "The like figure whereunto even baptism doeth also now SAVE us..."

What?  Water baptism SAVES us?  

Although I John 1:7 says "...the BLOOD of His Son Jesus Christ cleanses us from all sins?"  

With Hebrews 9:22 says

"Without BLOOD there is no remission?"

That's the FIRST misinterpretation.

CONTINUING I Peter 3:21

"...(not the putting away of the filth of the flesh but the ANSWER of a GOOD CONSCIENCE toward GOD,"..."

ANSWER?  We have to give GOD an ANSWER when HE "looks at hearts" (I Samuel 16:7)?

"ANSWER of a GOOD CONSCIENCE?"

When Hebrews 9:14 says

"How much more shall the BLOOD of Christ, who through the eternal Spirit offered Himself without spot to GOD,  ((PURGE))) YOUR (((CONSCIENCE))) from dead works to serve the living GOD?"

"OUR CONSCIENCE has been PURGED" yet we have to "GIVE GOD AN ANSWER FOR OUR GOOD CONSCIENCE?"

SECOND we have to "GIVE GOD ANSWER" when He doesn't need anyone to give Him a an answer because He looks at hearts?

THIRD we have to "give God an answer for our good conscience" that has already been purged?"

The rcc went HAYWIRE just making up shyt as they went alone and mankind just believe anything because it was in their "Bible."
