Think back to middle school math class. A Venn diagram is a graphic representation in which two or more sets of information are positioned beside and on top of one another. The overlapping circles include the information the different sets of information share. The Venn diagram is a good illustration for how we are to value friends with whom we have Christ in common. Christ should be the overlapping center we share with our closest friends. If those we are closest to are not connected to us by Christ, then we should consider asking ourselves why.
