1. On what biblical warrant can you point to that justifies your conclusion?
My position is as I stated, it speaks of being in Christ in Eph. 6:10. John 14:6 Christ is called the truth. Christ is the Word, which again is the truth, so I don't see that as stretching anything with our putting on truth. As for the breastplate of righteousness, Christ is our righteousness, we are clothed in His righteousness. Eph. 2:14, again He is called our peace and calling Him our salvation is by no means any stretch. Christ is all in all, and He alone is the only one mighty enough to stand against the devil and the evil forces. Our lives are hidden with Christ Col. 3:3, Christ prayed for our union with Him Jn. 17:21, Jn. 15:4 speaks of us abiding in Him, Or 1 Jo. 5:20 also speaks of being in Him, you already mentioned Gal. 3:27 etc. There are many scriptures which defend this positionally. Being in Christ is the only place of safety in this world. When are we defeated? it is when we step out of Christ that we become vunerable (no armour). I see no problem approaching it this way, there is a bigger problem using Hendrickson's method, making it subjective, synergistic as you say.
1) My sincerity is rubbish, my heart is desperately wicked, if I'm going to stand at all, it must be in Christ, not in any imagined ability of my own.
2) My righteousness is as filthy rags, I rest in the righteousness of Christ, His righteousness working through me, He is the vine we are the branches.
It just seems to me to be more about putting on Christ than anything else I read, I guess we'll have to disagree as usual. Gurnall is too wordy and he uses too much allegory, I didn't find it very much help having referred to it earlier.
