Sire
I have a long time, almost 30 years now very special friend of mine who is a foreign missionary.. He reaches Muslims with the Gospel every week.
I am waiting for another friend of mine who is a PHD to get some time and we are going to go fly over there to visit and help him for a week or two..
I take it you did not read where JESUS said to some skeptic that asked a similar question that "the very rocks and trees would cry out" to the glory of their maker.
There is no shortage of evidence of GOD in this world. All one need do is open their eyes and look and ask, how did this get here? How is it that we are the only planet in our solar system that is at the perfect distance from the sun and our planet revolves and rotates in a perfect distance around it so we do not get too hot or cold, and have such a diversity of LIFE on this planet and yet we find none on the other planets in our Solar System?
I was not born into a family that believed in Salvation is by GRACE thru faith, and not of ourselves. It is the gift of God, not of our deeds, lest any of us should boast.
Jesus said that the very ROCKS would cry out to testify of HIM and HIS Lordship.. It's not hard to see the wondrous works of God.. Or realize that everything about this planet did not happen by accident.
SO, I get what you are saying, but lots of Mooslims receive Christ as Savior every year. If one is seeking GOD, they really don't have to look very far to see the wonders of the works of HIS hands or HIS Glory.
Abraham witnessed about HIM to people and leaders of nations who did not know GOD and Abraham shared HIM with them.. God blessed Abraham because of his faith and faithfulness.
So it is with people today.. IF one seeks HIM, HE is very present and not willing that ANY should perish, but have everlasting life...
