- Ephesians 4:4 (KJV)
There is one body, and one Spirit, even as ye are called in one hope of your calling;
THIS is the heart of scripture, and also zeroes in on the problem man has had understanding God from the beginning. Man has wanted to divide people by race. From the first, man has taken what they knew of the one true God and tried to create a God for themselves instead. So God created a race to use to train man, and from the first (if you will do a search of scripture) God instructed to keep themselves open to all men who wanted to make Him their God. He told them over and over He was for the "strangers among you", too.
This training always included blood, the blood of Christ was always at the heart of knowing God. It was at the heart of sacrifices required for atonement, and atonement rather than full salvation was the best it could do, but it was always only through Christ. It was always grace that worked, never works that worked. It was always through faith and God as our power for living and salvation.
Because God tells us how to live in the best way possible, and our faith can't be kept completely separated from how we live out that faith, there is a terrible mix up in people's minds. When God assigned man to explain how things changed when Christ lived with us and wasn't represented in the sacrifices, the building of the temple, and the Levi priesthood any longer, and we were given the Holy Spirit so we didn't have to have the rituals to remind us any more, people are completely mixed up on knowing God. When they are told it isn't through certain customs they must live but in spirit and truth and the Holy Spirit, they say it is through denying and cancelling all God's word before Christ we should live in Christ. They call it Judaism and say all Judaism kills!!! These people separate Christ from the unity of God. They say it is ONLY through Christ, and if you recognize anything else of God, anything!!, you are denying Christ.
When Christ is taught as the key to our salvation, when the real Christ is shown who is one with God, all these offshoots of adding or taking away of scripture iron out and we have the true Christ and are saved through His blood!
