The word “we” is plural, meaning more than one. It is synonymous with saying the majestic “we.”
That statement makes absolutely no sense. Please try again.
I would hope that no theologian would simply make things up but would base their work on the knowledge and study of the subject in accordance with the structure of their discipline. You cannot prove that the “we” in Genesis is a reference to the Trinity, (keep in mind that the Trinity is not even mentioned explicitly in the New Testament) so you simply accept it because it makes you happy. In a way, you are simply making it up because it pleases you!
Did you ever once think that what you know about God, Jesus, the O.T. and the N.T. may be deficient and that there may be some things that have either escaped your knowledge or that you are simply ignorant about? I doubt that there are many religious scholars or theologians who claim to know everything possible about the subject.
We cannot believe anything unless we accept it with our intellect. If anyone is forging blindly ahead it is you and your insistence that Genesis refers to the Trinity when there are equally valid arguments against it.
Love of God does not stem from believing that Genesis refers to the Trinity. The Bible helps us in our quest but love of God comes from our heart and our intellect. Whether the “we” in Genesis is the majestic plural or not has nothing to do with it.
