A church is a group of people, a church is not a building, any group of people can be a church. A Christian is someone that is born of the Spirit (Jn 3:3-8), therefore the Christian church, the church of Yeshua the Messiah is the group of people that are born of the Spirit, the Christian church is spiritual, a Christian does not “go to church”, a Christian is the church.
John 3:3 The Messiah answered and said to Nicodemus, “Truly, truly, I say to you, unless one is born from above [born of the Spirit] he cannot see the kingdom of God.
3:4 Nicodemus said to Him, “How can a man be born when he is old? He cannot enter a second time into his mother’s womb and be born, can he?
3:5 The Messiah answered, “Truly, truly, I say to you, unless one is born of water and the Spirit [born of the Spirit] he cannot enter into the kingdom of God.
3:6 That which is born of the flesh [natural birth, born of man and woman] is flesh, and that which is born of the Spirit [Spiritual birth, born of God] is spirit.
3:7 Do not be amazed that I said to you, `You must be born from above [born of the Spirit].’
3:8 The wind blows where it wishes and you hear the sound of it, but do not know where it comes from and where it is going; so is everyone who is born of the Spirit.
The Christian church is the group of people that believe God’s Son, Yeshua is the Messiah, that no longer practice sin.

1 John 3:9 No one who is born of God [born of the Spirit] practices sin, because His seed [the Holy Spirit] abides in him or her; and he or she cannot sin, because he or she is born of God [born of the Spirit].
