Eating together with other believers helps us to be whole because it ministers to the body and spirit. From a practical standpoint it is also another daily event to bring the Lord into. Use meals, as well as other recurring events to build in spiritual opportunities. Praying before your restaurant meal is also another way of being a visible Christian, although we aim much higher than a before meal prayer for the fellowship of believers with Christ and each other. That brings us to the last item we are looking at in Acts 2.
Christians pray together.
Be open for prayer opportunities. Prayer brings in another player. As we meet together we also need to know each other well enough so that we can pray for each other effectively. This means being honest and open about our triumphs and failures. It means being open to the opportunity, as well as the vulnerability, needed to pray with each other.
