How can Christians and Muslims learn to fully respect one another?

For Christians, Jesus is the center of their spiritual experience, the heart of their devotion, the fulness of the Godhead bodily. For Muslims, God does not beget nor is he begotten. Christian monotheism is more complex and philosophical. Muslim monotheism is simple and absolute. Neither Christian nor Muslim who is devoted to his faith is going to change his devotion. So how do we live with mutual respect without condemnation and suspicion of one another? How do we not just "tolerate" each other, but appreciate each other's faith and traditions?
