Did you become a Christian to be a part of the body of Christ, or for some other reason? Some people become Christians because of peer pressure, others because of family tradition, popularity and the like. What about you? If it was not to follow, and obey Christ all the days of your life, then you are not a Christian. Christians have a personal relationship with Jesus Christ as their Lord and Savior. To become a Christian one must have a change of heart and mind. One must be born again; spiritual birth through faith in Jesus Christ and His finished Work on the Cross (John 3:3). The Kingdom of God is for all who have personally repented. If one is not born again he cannot, by association with Christians , see the kingdom because the kingdom is comprehended in the heart of the believer (Luke 17:21).
Work Out Your Own [Soul] Salvation
No matter where in the world you are, repent and get to know the True and Living God. Continue on into maturity in Christ. "....work out your own salvation with fear and trembling (Philippians 2:12). Stay clear from false doctrine and those who teach anything other than Jesus Christ and Him Crucified. Dissociate; part, cease or break, from world views, false doctrine, and Antichrists. Remember, even a small amount of false doctrine will consume the entire message of the Cross. "A little leaven leavens the whole lump (Galatians 5:9). "But we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles (1 Corinthians 1:23).
A Little Leaven Leavens The Lump
For this reason, "They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us (1 John 2:19).
This scripture does not pertain to a Christian leaving a particular place of worship in his or her community. It pertains to those who succumb to false doctrine and as a result turn their backs on Jesus Christ.
True Christians [followers of Christ] obtain faith by hearing the [unadulterated; no leaven] Word of God (Romans 10:17). They know that fellowship begins with Faith in Christ Jesus and His finished Work on the Cross. A true Christian knows that as long as he is born again, worships God in Spirit and Truth (John 4:24), and his fellowship [wherever it may be] is one where Jesus is the only One being worshiped (Deuteronomy 4:24), the fellowship [with Jesus and true brethren] remains.
