John, nor does the word of God contradict itself..either someone is the righteousness of God when repentant...or they are not...
So for man to dictate how a righteous man can and cannot be used by Holy Spirit makes no sense...so the passage you are standing on only works if YOU interpret it that way..that was discussed several pages back.
David's live is not a NT ministry model..but it is rue an awesome revelation of the character of GOD...that has not changed...God does not hold to double jeopardy....yes you are forgiven and clean but I still have to punish you by withholding your gifts and calling...
