So, in other words. You can't prove me wrong in Romans, so you jump over to 1 John 1?
Ever heard of the Royal "WE", Jerry? Like "we" need a bath, today." Or it's time for OUR bath..... when talking to someone in an old folks home, for instance? "We" both are not taking a bath.
Was John using the so-called Royal "We" here?:
"That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; (For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us) That which we have seen and heard declare we unto you, that ye also may have fellowship with us, and truly our fellowship is with the Father, and with his Son Jesus Christ" (1 Jn.1:1-3).
Anyone with the slightest bit of discernment can understand that pronoun refers to believers. And there is no reason to suppose that the identity of the ones referred to as "we" ever changes in the verses which follow:
"And these things write we unto you, that your joy may be full. This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us" (1 Jn.1:4-10).
According to you the pronoun "we" changed from referring to believers to referring to unbelievers at verse 6.
And then in an attempt to cover up your blunder you speak of a Royal "We."
All you prove is that in order to cover your blunders that you are willing to say anything, no matter how ridiculous!
