The neighbors of the early Christians saw the Christians as a cult. They believe the Christians were a people obsessed with this famous figure (Jesus) that died, and they wanted to bring him back to life. They would sacrifice themselves, their personal lives, in order to see this Jesus live again. These Christians would gather only for one purpose—to be possessed by the Spirit of this Jesus, so that he would continue to live out his life through them. This would be achieved through a ritual of eating Jesus' flesh and drinking his blood. To the neighbors, Christianity is an occult system to bring back a dead man, not in his body, but the body of the followers. Just take some time to think of this view.
Sure we know that Jesus isn't really dead, he resurrected. But to the world he is dead, they can't see him or interact with him. However, we can, and we are his body, do you know what that means? If a person doesn't have a body then you can't see him or interact with him, he is dead to you. A body would make him alive to you, for you will be able to see him express himself, and you will know him and interact with him. We are Jesus' body, called to express and manifest him to the world.
We are called to be filled with his Spirit and become the body through which he would continue to walk the earth, doing good everywhere he goes, just as he used to do before his death. Jesus is the same yesterday, today and forever (Heb 13:8). He wants to do the same thing he was doing before his death, resurrection and ascension. He wants to heal the sick, raise the dead, love the sinners, cast out devils, preach the Kingdom, and so on. He wants to do all these things through the Church, his body. But this body needs to function properly so that he could do all that he wants to do through it, that is why he had made provisions for the equipping of the body into a fully mature and perfect body.
"Now these are the gifts Christ gave to the church: the apostles, the prophets, the evangelists, and the pastors and teachers. Their responsibility is to equip God’s people to do his work and build up the church, the body of Christ. This will continue until we all come to such unity in our faith and knowledge of God’s Son that we will be mature in the Lord, measuring up to the full and complete standard of Christ." (Eph 4:11-13).
The body of Christ must be in the full and complete standard of Christ, so that Christ can effectively express himself through it. A dog needs a mature dog's body that is in the right standard, so that it can properly express itself in it. Put a dog in a fish body and you will have a serious problem. To properly express himself, Jesus needs a body that is in his own standard. And what is the standard of Jesus? Raising the dead, healing the sick, living righteously and holy, exercising authority over demonic powers, weather, and every natural and spiritual thing—that is the standard of body that Jesus needs.
He needs a body that can move in the supernatural and do all the things that he wants to do, that is why he has made provisions for the edification of his body to attain this standard. When you became a Christian you gave your life away and you received Jesus' life. As such, it is all about Jesus living, not you. Christianity is about giving Jesus a mature and standard body so that he would continue to walk the earth and do the things he wants to do. This is the course you give your life for. The moment you became born again you sacrifice your life for this very course, now all that matters to you is to see Jesus live through your body.
"I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me." (Gal 2:20).
The Christian faith is all about sacrificing yourself so that Christ might live through you. Yes, you sacrifice your life, your ambition, your dreams, your comfort, your desires, your plans, and everything entirely. You die, oh do you know what it means when a person is dead? Everything dies with him, his ambition, dreams, talents, pursuit, everything dies with him. That is what happened to you the moment you became born again. You died, and as such, it is no longer about you, but about Jesus. It's no longer about what you want or don't want, what you like or don't like, what you feel or don't feel, all of that don't matter anymore.
The only thing that matters now is that Christ should live through you. So you give yourself to that, whatever it takes, you pursue it. You now want to give him a mature and standard body, so that he can effectively express himself and live through you. As such, you pursue spiritual maturity, you desire to grow into that mature and standard body, you do whatever it takes to become that body—oh, that Christ might walk the earth through you in all of his fullness and glory.
