Key Verse: "But ye are not in the
flesh, but in the Spirit, if so be that the Spirit of God dwell in you.
Now if any man have not the Spirit of Christ, he is none of his"
- Romans 8:9 KJV
Our possession of the Holy Spirit is the very essence of what it means to be a Christian. As noted in our Key Verse above, if anyone does not have the Spirit of Christ, he does not belong to Christ. Those who belong to Christ have the Holy Spirit living within them. Moreover, if you have Him indwelling you, you will live like Him (vv. 10-13).
