Many Muslims recognize Christ as a prophet and therefore feel that Christmas is okay to be recognized also. I pray that many of them will come to know Him for who He really is. This will happen if more Christians will witness to all lost people.
Yes, I pray for Muslims worldwide, that their hearts will become open to the Holy Spirit and good news of Christ.
Many years ago I sat at a lunch counter reading my New Testament. The young man next to me noticed it. He said he was a Muslim. I didn't know anything about Muslims back then, but I proceeded to explain God's plan and the promised Messiah/Savior beginning in Genesis. A couple of months later, this young man came over to me at the lunch counter and said "I just want you to know I became a Christian."
So some come to Christ so fast....and with others we must share in love and have patience, and pray that God will give the increase.
