Scriptures don't all say exactly the same thing. Different prophets emphasize different principles at different times to different people. But the scriptures taken as a whole paint only one picture. The picture comes to us in many small pieces, as if a puzzle, but they fit together perfectly until they seem inseparable. When the big picture finally comes into view, we see as we have never seen before. Through the spirit, we see the plan of salvation as it was planned in the pre-mortal sphere, as it was foreordained, as it was prophesied, and as it was realized.
Hereby, truth becomes timeless and is circumscribed into one great whole. There are few spiritual experiences which are more powerful than comprehending God's truth in one. We are reminded of the two disciples on the road to Emmaus. The Lord taught these, beginning at Moses and all the prophets, he expounded unto them in all the scriptures concerning himself. We should not be surprised that their increased vision was accompanied by a profoundly spiritual experience, And they said one to another, Did not our heart burn within us, while he talked with us by the way, and while he opened to us the scriptures? (Lu 24:27,32)
Mormon later records, 'And he did expound all things, even from the beginning until the time that he should come in his glory-yea, even all things which should come upon the face of the earth…And now there cannot be written in this book even a hundredth part of the things which Jesus did truly teach unto the people' (3 Nephi 26:3,6).
