What is a Church?
Christians are the church! When you receive Christ and believe he died on the cross for your sins, you will want to put away the sins that you once committed like lying, having sex, stealing and whatever you were doing against God. The ten commandments which explains the laws Christians need to live by are in the book of Exodus. The book of Exodus goes through each one thoroughly. In the new testament Jesus said, that there are two of the greatest commandments that all the laws and prophets hang on to; the first is love God with all your heart and with all your soul and with all your mind. The second is love your neighbor as yourself. Matthew 22:36-40
Once you have decided that you are ready to put the old you away, you will get baptized in the name of the Father, Son, and the Holy Spirit. After you are baptized you become a new creature in Christ and receive the Holy Spirit in you. 2 Corinthians 5:17 Therefore if any man be in Christ, he is a new creature, old things are passed away; behold, all things are become new. Since the Holy Spirit came out of Christ body when he resurrected and is placed in us once we get baptized our bodies become a living Church.
Once you become more in tune with God you start to show Spiritual gifts that is supposed to be used to edify the church community and to help non-Christians understand Christ. 1 Corinthians 6:19-20 he asks "Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.
Also because as Christians we are the Church when two or more Christians come together in the name of Jesus he is their. The presence of the Holy Spirit becomes more intense and people have different experiences with the Holy Spirit. I felt it so strong once and I passed out. It is a good thing to have the Holy Spirit and feel his presence because that means you are closer to God.
Matthew 18:20 "For when two or three gather in my name, there am I with them."
