The Apostle Paul said: “The Lord knoweth them that are his” (2 Timothy 2:19). “Now if any man has not the Spirit of Christ, he is none of his” (Romans 8:9).
“Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you?” (2 Corinthians 13:5). “For ye are all the children of God by faith in Christ Jesus. For as many of you as have been baptized into Christ have put on Christ. There is neither Jew nor [Gentile], there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus. And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise; that the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith” (Galatians 3:26-29, 14).
“For therein is the righteousness of God revealed from faith to faith: as it is written, the just shall live by faith” (Romans 1:17).
“Now the just shall live by faith: but if any man draws back, my soul shall have no pleasure in him. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul” (Hebrews 10:38–39).
“For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ” (1 Thessalonians 5:9).
“For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first, then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord” (1 Thessalonians 4:16–17).
“Wherefore comfort one another with these words” (1 Thessalonians 4:18).
