What follows is a very clear and very simple explanation of the basic differences between the Body of Christ and those who are working on getting saved.
How I wish that all those who are working out their salvation, or who don't even think of what will happen after their lives on this earth, would understand this simple Gospel.
Half of all those who wear a badge proclaiming their "Christianity" are Catholic, and another bunch are Orthodox. Of all who stand outside the pale of true Christian faith, there can be little doubt that those who cling to these apostate religious systems are never going to be able to earn, win or buy salvation. Would that they really READ the Gospel and study Scripture instead of watching "faith dealers" and being charmed by wolves in religious clothing.
Who is a Christian?
There are two billion people on the earth who identify themselves as Christians, but there are significantly fewer that are really part of the body of Christ.
Jesus said you can not enter the kingdom of heaven unless you are born of the Spirit. The new birth from the Holy Spirit occurs when a person truly believes that Jesus is the son of God and trusts in the finished work of Jesus on the cross to atone for their own sins and to justify them before God.
The scriptures say you are saved by faith, not by your own works, lest anyone should boast.
We cannot judge if a person who identifies with Christianity is really trusting in Christ or in their religion to save them. If they are trusting in their religion to save them they are no more part of the body of Christ than a Jew or Moslem or any other religion.
Christianity is a personal relationship with Jesus. This relationship does not depend on having all the correct theology but correct theology will result in more fruitful Christianity.
Religion is basically satanic
All religion contains methods, rituals and practices for man to become righteous enough to ascend or evolve to God. All religion thus believes in the need for one to become self righteous. True Christianity is the complete opposite. True Christianity believes in God's righteousness. Because of His righteousness, Jesus the creator, died for our sins and breached the gap between God and man. True Christianity believes God provides a free gift of eternal life to anyone who trusts in Him (has faith) that God is graceful and sent His Son to save those who believe in His righteousness.
Apostate Christianity (departure from true biblical Christianity) in its final analysis cannot be distinguished from any other religion in the world in its quest for God. No wonder apostate Christianity will be willing to join with all the other religions of the world. These nominal Christians think they are Christian just because it is part of their culture and because they believe in a higher power. Even demons believe in a higher power. Apostate Christianity has nothing to do with a born again experience with the evidence of a Holy Spirit changed life.
Some in religious training were taught that Jesus died for their sins and that they are saved or justified, but in their lives there is no evidence by works of the Spirit. Do they really have Jesus or do they only have head knowledge about Him? Do they have Churchianity or Christianity?
Those that trust in their own good works to save them are self deceived and still in their sins. If there ever was a religion that could allow man to fellowship with God it was Judaism but the requirement was to keep all of God's law. The laws of Judaism did not achieve salvation because in man's fallen state he could never keep the whole law. Man's righteousness and good works can never bring about eternal life with God because man always falls short of the required perfection necessary to dwell in the presence of a Holy God. Yet Judaism did not fail because through the tribe of Judah a Savior from God was born.
Jesus being born a man but being also God perfectly fulfilled the law. He Himself had no sin but He obediently paid the price for the curse on man under God's perfect law. Atonement for sin brought into the world by Adam's disobedience was paid for by the obedience of God's Lamb by death on the cross. At the cross He took the curse upon Himself for it is written " cursed is anyone who hangs on a tree" (Gal 3:13). Death could not hold the Creator and He rose to begin a new creation and in doing so condemned the old fallen creation to its eternal destruction. Those who trust Him are born again into this new new creation of believers called the "Body of Christ". After we are born into this new creation, God no longer sees us as the sinners we were but He sees us as the sinless "body and bride of Christ". (The scripture says in marriage the two shall become one flesh - Paul used this as the example of Christ and the Church - Eph 5: 31- 32.)
"True Christianity is then believing that God's promise to provide a Savior was fulfilled in His Son Jesus." This promise of a Savior and Messiah to restore man's fellowship with God is integrated throughout all scripture.
