Sir, you are a classic case of a spiritual nit picker! If you go back and read my post, you will notice that I never said or insinuated that the blood exclusively was sufficient.
However, I do want to say that there is power in and through the blood!
Acts 20:28 We are purchased by His blood.
Rom 3:25 There is propitiation through His blood.
Rom 5:9 There is justification through His blood.
Eph 1:7 There is redemption through His blood.
Col 1:20 There is peace through His blood.
Heb 9:14 There is purity through His blood.
Heb 9:22 There is remission of sin through His blood.
Heb 13:12 There is sanctification through the blood.
Heb 13:20 There is a perfecting that comes through the blood.
1Jn 1:5/Rev 1:5 We are washed from our sins by His blood (purity).
I should be able to say that without having to explain of defend myself. Let me go ahead and say though that all of these things are provided by the blood, but they are applied to our lives by the Spirit. As John wrote, "The Spirit and the blood are one."
Just because I did not lay out an entire theological foundation that included the "whole" picture, does not mean that my earlier statements were false.
Please do not assume things about me that I haven't stated.
As to your statements about sinning Christians,I know that the potential for a believer to sin is always a possibility; however, because of grace, the blood, and the Spirit, we have been freed from the power of sin. "Sin shall not have dominion over you - for you are under grace (Rom 6:14). I would also encourage you to do a word study on words like Justification, sanctification, remission, and cleansed. Also, you will notice that every time the scriptures speak to this matter, it always speaks in the past tense, in regard to believers. "You were........, but now you are washed, sanctified, and justified. If that does not show up in ones life, then the terms are void of any real meaning.
