So whether you read these 500 quotes or not, you will never understand Christianity without reading The Scriptures in their entirety.
Maybe not. Maybe it doesn't matter if anyone understands Christianity. You yourself reject a major tenet of mainstream Christianity, the Trinity. And 80% of "The Scriptures" is the scriptures of the Jews. So maybe reading The Scriptures in their entirety would cause one to understand Judaism 80% and Christianity 20%. I really fail to see how reading a book in its entirety which is 80% the Hebrew scriptures will cause anyone to understand Christianity. There must be some un-said assumptions here.
Maybe all they need is to know what they need to do to attain eternal life, that information directly from Jesus, not from Paul or Peter or Moses, etc.
Oh, here it is:
...Master, what shall I do to inherit eternal life? (Luke 10:25)
"Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbor as thyself." (Luke 10:27)
"Not every one who says to me, Lord, Lord, shall enter into the kingdom of heaven; but he who does
the will of my Father who is in heaven." (Matthew 7:21)
The only ones who will enter the kingdom of Heaven, according to Jesus, is "he who does
the will of my Father." So simple. Throw the rest out, imo.
