The church is a called out gathering of God's people; when He calls, we respond
We must guard our unity, since the devil seeks to cause division
Paul's intenerate ministry was of and for the Body of Christ.
Welcome one another for building up, according to the example of Christ and the Old Testament prophecies
We should care for one another's consciences in order to build one another up 14:13-23
We should receive one another for the sake of fellowship in the body of Christ and leave judgment of secondary things to the Lord.
We need the communal setting of God's people in order to fully develop as Christians
We have been called together, not for a club, but for a purpose.
Jesus expects us to follow Him in the midst of other, imperfect people.
When Jesus says, "Come follow me," He leads us to Himself, to community with other Believers, and to outreach to the world.
