From previous post of yours I believe I know the answer to your riddle :) Not sure if you want me to spoil the surprise though brother. But in regard to my mighty weapon it will always be the weapons Christ has given me and the armor He has given me. The Word of God is sharper than any double edged sword.
K prayer n Gods word, I GUESS
I would have to say that it is the Bible. It cannot be the sword of the Spirit, because the sword of the Spirit (as the word) will always be used in the right "Spirit." However, we know that the letter killeth, but the Spirit giveth life. Therefore my conclusion is that it has to be dangerous when we use the Bible to bring death. But it can be the sword of the Spirit when lead by the Spirit. That is why those who are lead by the Spirit are the sons of God, and if you are not lead by the Spirit you are not a son (or daughter) of God. This is why not many should be teachers knowing they shall receive the greater judgment should they be "Super Apostles" of presumption. Jesus seeks those who would worship him in Spirit, and in Truth.***Edit*** Great question Brother.
Ooohhhh, I think Grant has me licked...
