Really?
Instead of you using your own logic and common sense, perhaps you should see what the bible says about it...Oh, that's right, you guys don't believe God...
1Co 7:6 But I speak this by permission, and not of commandment.
1Co 7:7 For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.
So we can believe your common sense, or, we can believe God...
2Pe_1:21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
Mat_5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
God approved of every word, including every and, if, by, to and ignorant...
What you think about it means nothing...
Evidently they don’t believe it’s “God’s word” but rather some of it is Paul’s word, some is Peter’s word etc.
