The reason there are so many exhortations for Christians to love other Christians in the New Testament is because the Church is not made up of natural friends; it’s made up of natural enemies. What binds us together is not what binds together any other human community. Christians come together not because they form a natural collocation but because they have all been saved by Jesus Christ and owe him a common allegiance. The Church is a band of natural enemies who love one another for Jesus’ sake. Be patient. It will take time. Your heart needs it. And Jesus has the power for it.
