I believe God can and does raise the dead, but…
…I still do funerals.
This is my stance on marriages ravaged by infidelity. I believe some can be resurrected; however, that is a miracle. It is about as common as a funeral ending in a resurrection today.
That is to say, not common.
The natural course of things following marital infidelity is the ending of a marriage via divorce.
Can God do a miracle? Absolutely.
