Well... some muslims may know more of God's truth than some christians. Anything is possible with God.
Look at the "christians" who paint a sadistical, evil, schizophrenic picture of God.
Truth is truth no matter what type of building a person is sitting in, or what name they mistakenly call someone.
No one sees clearly. T'is far better a muslim seeking love than a christian seeking vengenance.
What difference does it make if a mosque is being built or a church is being built?
Who cares? Human beings have a right to seek out and find truth in whatever way they can.
We are all brothers and sisters at our core, just trying to make it back home.
Revelation 7:9 After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands; 10 And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.
