I agree.
I have a friend who has been a missionary to the Muslim world for nearly 30 years now. He spent twenty years somewhat "undercover" working as a contractor in one Muslim country. His ministry was simple: He behaved as a Christian so that it was clear that he was a serious believer, not merely the typical American "default" Christian.
But every now and then, he was quietly approached by a Muslim who wanted to know more about Jesus.
So what my friend would do is simply begin reading with the Muslim through the gospels, each one from Matthew through John. They they would read through Acts, then Romans. They just read. My friend would answer questions simply, but mostly they just read. It would typically take months, with the Muslim returning on his own to continue.
Most importantly: My friend never tried to expound Christian "theology" or "doctrine." You see, the Quran explicitly inoculates Muslims against Christian doctrine. It spells out responses to specific Christian assertions about Christ--and Muslims love to get Christians into those debates because they already have their ammunition.
But my friend just read scripture. When they finished Romans, he would ask, simply, "Do you believe what we've read?" He reports that every Muslim who stayed with the reading from Matthew through Romans said, "Yes, I believe this. I want to be baptized."
