Nice postsThat was the purpose of God, to go to the sinners and preach the Gospel of the Kingdom. There is no command to not associate with sinners. We would have to be apart from this world for that to be possible. The position of the Church was one of a priesthood and Sonship and heirs of God to the Throne of God. And It was offered to the Priest and religious leaders who knew the Scriptures and should have heralded in and been witnesses of the Christ, for He came unto His own, (religious leaders) But His own received Him not. (John 1:10-11) They did not want to turn over divine authority to the Christ, but wanted to keep it for them selves. (Matt. 21:33-46) But to those who did receive Him, He gave them power to be Sons of God (John 1:12-13). So Christ called those to inheritance that were not originally intended because The religious leaders rejected Him as King and forfeited their position. (Matt. 21:38-44) Now, there is a command to have NOTHING to do with some one who says he is a brother , who live and practice by the principles of this world...do not even eat with them, (1 Cor. 5:9-13).
God is not saving the world at this time, He is creating His Church (body of believers in His image) The Church is called out by the Lord as Son's of God.(Rom. 8:14-17) And the Gates of Hell can not come against it. The Lord said that, not me. (Matt. 16:13-19) And only the Lord adds to His Church...And once the fullness of the Gentiles have completed the Body of Christ, the body will be complete. (Rom. 11:25) The saving of mankind will be after the Church returns to heaven with the calling of the Lord, Then the multitude of men, that can not be counted, will be save of all nations. (Rev. 7:9-17) This is what The Lord teaches. Man teaches another Gospel. Study the proof Scriptures above...They are clear! I tell you, quit following the Doctrine of men and ask the Lord to lead you to the Truth. If you truly are sincere, everything material that you have put your trust into will be taken from you, till there is nothing left to cling to but the Lord. BTW, The religious leaders of Israel knew the Scriptures, and they also knew that Jesus was the Christ, they just straight out rejected Him to keep their status of importance and praises from the people. (John 3:1-2).
God leaves a remnant, so is everyone in every Christian church going to wind up in heaven? It doesn't seem so. But that considered, we need to be careful coming against other Christian denominations!
