Qur'an Surah III: 51-53 True Christians are Muslims
Jesus said: "It is Allah who is my Lord and your Lord; Then worship Allah. This is a way that is straight."
We find in the words of the Prophet Jesus, PBUH, clear testimony that all beings, no matter how exalted in the universe, or how divergent in their paths, have the same One Lord. The Apostle Jesus testifies that Allah is "my Lord and your Lord." It is a statement that is not based on the views or opinions of humans, or the particular religious affiliation. There is only One Lord, and that One Lord is the Lord of All.
After finding unbelief in them (meaning a rejection of the the Oneness of God who is God of All), he said: "Who will be my helpers to do God's work? [Some in the crowd answered]: "We are God's helpers. We believe in God and bear witness that we are Muslims."
There are a couple of interesting points here that we should meditate on: First, God (the Light) invites us to serve as helpers. To be a disciple of Jesus is to help the Light to manifest in this dense world of matter. Our duty as disciples of Jesus is to pull Spirit down into Matter while raising matter up towards Spirit. This is the work of a helper. Second, by progressing on this path of being a helper, one becomes a Muslim, namely: one who has entered into a state of surrender. To be a Muslim is a totalizing existential state.
Both mainstream Christians and Muslims should take heed from these sections of the Holy Qur'an. Both groups make the mistake of how one becomes a "disciple." Evangelical Christians mistakenly believe it is a matter of simple belief in the work of Christ on the cross, when in fact it is about becoming a co-worker with Jesus. Most Muslims today mistakenly believe that one is a Muslim if one adopts a certain dress code, performs prayers in a certain way, keeps the law, customs. In fact, being a Muslim is to be in a state of complete surrender from within the heart. We Muslims must move from the exterior to the interior; we Christians must move from simple phrases that excuse oneself to acts or deeds of kindness and compassion in this world.
Christians and Muslims yoked together could prove to be a powerful force against the forces of darkness.
