Living in Christ
Those living in the anointing of Christ: 1 Corinthians 1:2 To the church of God which is at Corinth, to those who are sanctified in Christ Jesus, called to be saints, with all who in every place call on the name of Jesus Christ our Lord, both theirs and ours:
This is a very good verse for us to use to understand whom our brethren are. Note that there is no distinction of corporate church affiliation but rather those that are calling upon our Lord Jesus Christ for their daily divine direction by the grace of God that is found in the blood of God's Son, Jesus, our Lord and Savior. Very simple here, our brethren are those that have a sincere prayer life, seeking and submitting to God's will through the name of His Son, Christ Jesus, our Lord and Savior. These will be known by their zeal for good works in Christ.
Romans 8:5.For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit, the things of the Spirit. 6. For to be carnally minded is death, but to be spiritually minded is life and peace. 7. Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. 8. So then, those who are in the flesh cannot please God. 9. But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His. 10. And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. 11. But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you. 12. Therefore, brethren, we are debtors not to the flesh, to live according to the flesh. 13. For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live. 14. For as many as are led by the Spirit of God, these are sons of God.
The last verse says it all. This last verse is so ignored by so many of the doctrines of men. There is a great resistance to that verse. Stephen identified it this way, just moments before the religious mob killed him.
Acts 7:51. "You stiffnecked and uncircumcised in heart and ears! You always resist the Holy Spirit; as your fathers did, so do you.
