Acts 2:42 And they continued daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart.
Fellowship is more than an association which exists in secular groups such as a civic club. There’s a large difference between community participation and spiritual participation and being in one accord. The difference lies in the fact that the Holy Spirit is within the Christian believers. He creates a spiritual union by molding the heart of the believer to the hearts of other believers. He attaches our lives one to another. Through His Spirit, we become one in life and purpose. We share blessings and gifts.
Fellowship forbids an unattached Christian life. Christianity is first an individual matter, but then it becomes a social matter. We are attached to Christ individually, but we are also attached to other believers. Christianity is first a spiritual organism but then becomes a spiritual organization. We have an inward life but we also take on an outward form of life. We become a living organization with other believers. Christianity makes me a saint, but Christianity is made up of saints. Christianity requires we live out virtues such as love, kindness, and patience. We can only do this in relation with others.
God Himself requires that we be in fellowship with other believers. What a gift this is for us! To find likeminded brothers and sisters – to feel our hearts being knitted one to another – to be accepted and understood – what a wonderful blessing this can be if we will only allow the Spirit to draw us unto each other.
