Outreach must be intentional and continuous. Evangelists are people who do the tough thing first. They prioritize reaching new people. Assimilate people into fellowship groups. Existing groups tend to resist newcomers.
New groups tend to absorb new people.
Supply lots of reasons to get together. Multiply opportunities for fellowship. Only a few things are essential to the life of the church. Those essentials should determine schedules, priorities, and activity level. We're not simply to be busy, but about the Father's business.
