I don't think we have to understand every aspect about God...or even most...to be saved.
This thread has a serious layer of dust on it! The truth is, that we do not need to know one thing in order to be born of God. For all men are dead in trespasses and sins! Now, if we profess to be born of God, and deny the deity of Jesus Christ, being the I AM THAT I AM, then we reject the very cord of the gospel message, that the Son of God, (that statement making him equal with God in his Divinity) is the only
propitiation for the sins of his people. Truth comes to God's children over long period of time, and even then, they are not fully converted to a knowledge that is absolutely perfect according to the teachings of the holy scriptures. The apostles during the days of Christ were pitiful in their understanding, and even Peter at the end of his life, still found many truth hard to grasp hold of!
2nd Peter 3:15,16~"And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction."
I have found that very few truly understand the doctrine of the Godhead, yet many of them are children of God....the one's that are not
his children, are the very ones that denies Jesus' deity as the Everlasting Father of all things
