There are over 50 specific references to doing something with 'one another' in the New Testament and nearly all of them relate to the church. (1 Corinthians 7:5 instructs husbands and wives not deprive one another of marital intimacy.) As you look at each one of these imperatives consider how obvious it is that Christ and His Apostles intended for Christians to be in a church, an assembly of believers, where each of these "one another's" can be lived out.
