Dr. Albert Mohler answers the question, “What about denominations?” The skeptic and church critic wants to know. 
He begins by quoting Sydney Mead, a church historian. He says, “Theological conviction plus religious freedom equals denominationalism.” It is a simple math formula that describes why we have so many different denominations in the world.
Mohler adds the caveats that the differences in theological conviction is not about the authority of Scripture, the nature and work of Jesus Christ, or the creeds and doctrines of the universal church. This is how we make a distinction between churches that claim to be Christian, i.e. Jehovah’s Witnesses, Church of Jesus Christ and Latter Day Saints.
Though there are many denominations with different theological convictions we do have a foundation upon which we all stand: Jesus Christ. Through him we all can come together, work tougher, and see the kingdom of God in our world. Our diversity actually helps us in bringing the kingdom of God to our world. Our different perspectives, different strengths, and our combine resources will go far in advancing the kingdom of God.
Bob Ekblad says, “It is urgent that people from diverse sectors of the global body of Christ humbly learn from one another and partner when possible. God’s kingdom will break in sooner and with more power to a desperate world as people serve each other in unity.” 
Working together will only bring about the good for the Church, good for our neighbors, and good for the kingdom. The time is now to begin to work together in unity to see the kingdom of God come.
