I'd like to mention in brief some of the main differences between Islam and Christianity:
1. The God of Islam is Allah. Allah is monotheistic. The God of Christianity is also monotheistic, but unlike the God of Islam, the God of Christianity is the Triune Father, Son, and Holy Spirit. God therefore is three Persons yet one God.
2. The prophet of Islam is Mohammed. The Prophet of Christianity is Jesus Christ. Jesus is also Christianity's Priest and King.
3. According to Islam Jesus is a prophet. According to Christianity Jesus is God. He is the Middle Person in the Triune Godhead. Jesus is the Word who became flesh, who is like us in every way apart from sin.
4. According to Islam a person pleases Allah by doing his will, by keeping Shariah law. According to Christianty a person gets right with God through Jesus Christ's perfect keeping of God's Law, which righteousness is imputed to believers. Which is to say that we are condemned because we break God's Ten Commandments, but "God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life."
