From Scripture, the reason for our existence as a church can be determined to be the following:
Communion with God—To love, honor, worship and serve the Almighty.
For He chose us in Him before the creation of the world to be holy and blameless in His sight. In love He predestined us to be adopted as His sons through Jesus Christ, in accordance with His pleasure and will—to the praise of His glorious grace, which He has freely given us in the One He loves.
Community of the saints—To love, fellowship with, build-up and serve God’s people.
It was Him who gave some to be apostles, some to be prophets, some to be evangelists, and some to be pastors and teachers, to prepare God’s people for works of service, so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.
Communication to the world—To love, witness to, influence and serve those
yet to receive God’s saving grace.
For He Himself is our peace, who has made the two one and has destroyed the barrier, the dividing wall of hostility, by abolishing in His flesh the law with its commandments and regulations. His purpose was to create in Himself one new man out of the two, thus making peace, and in this one body to reconcile both of them to God through the cross, by which He put to death their hostility.
