Muslims have a lot in common with Christians: they believe that there is only one God, who revealed His will to humankind throughout the ages; they believe that God created the world, that He sustains and directs it, and that we should live according to His will.
Muslims are against abortion, they want to protect marriage, and they are very zealous to win others to their faith. In fact, Muslims believe they are the best of people and that Islam offers the world a solution after Christianity failed.
There are also a lot of differences between the two.
Muslims have a different concept of major characteristics of God, of law and sin, of heaven and hell, and on how to enter the heavenly realms. In their practice they seem very devout. They pray five times a day, fast during the day for a whole month, do good deeds, and want to visit their holy places at least once in a life time.
Christianity seems a much more internal spirituality that is not always seen from the outside, even though Jesus said love and unity are the marks of true disciples.
