Another one who implies faith is irrational.
All those millions of Christians in dire need of a rational proof. You should start a ministry to send missionaries to the world’s Christians so they no longer have to rely on trust in Christ but can cite a nice solid metaphysical proof. For that’s the work of the Lord, let’s have done with amazing grace, may the light of symbolic logic shine on the kingdom!
I am genuinely puzzled by your either/or - only one or the other - constraint on spreading the Gospel. Take, for example, Stephen’s witness in Acts 6:8.
And Stephen, full of grace and power, did great wonders and signs among the people.
Then some of those who belonged to the synagogue of the Freedmen (as it was called), and of the Cyre’nians, and of the Alexandrians, and of those from Cili’cia and Asia, arose and disputed with Stephen.
But **they could not withstand the wisdom **and the Spirit with which he spoke. (Acts 6:8-10)
Notice that he used “great wonders and signs,” but also that he “disputed” with them (like tango, it takes two to dispute) and “wisdom” was, in the end, what “they could not withstand.” So, the lesson to be taken here, is that wisdom is mightier than signs and wonders, no?
In fact, the entire first 53 verses of Acts 7 are Stephen laying out a point by point argument from Scripture and history to make his case by appealing to their sense of reason (aka wisdom.)
Now, granted they stoned him after that, and you might be able to make a compelling argument that dropping a mountain on their heads would better serve to cure their “stiff necks” (Acts 7:51), but that does not support your larger claim that we are restricted from using reason to spread the Gospel (which Stephen did,) but are, rather, constrained to dropping mountains on their heads. Stephen, after all, was a saint and martyr not because he moved mountains, even though he ended up being buried under one.
Well, come to think of it, perhaps moving mountains would have come in handy at that moment, but still that does not make your case that reasoning is not to be used and displaced by faith alone, even where that involves excavating mountains miraculously.
Surely, it isn’t your claim that because Stephen didn’t make the mountain of stones “move from here to there,” he didn’t have any faith to speak of, not even the size of a mustard seed, are you?
