Well I think there is a difference between the “signs” as mentioned in the Matthew text and miracles that God had wrought thru the apostles at least after Christ returned to heaven and the Holy Spirit was sent. The pharisees sought some overwhelming proof that their world view was incorrect hoping against hope that Jesus was false because the pharisees were so comfortable in their perverse corruption. That is what Jesus was confronting where he declared that only the sign of the resurrection would be given to them.
There certainly have been miracles since Christ went back to heaven even after the times of the apostles but most are not necessarily big and splashy! True, not everyone who gets prayed for gets healed but many Christians can attest to sudden reversals of lab tests or of tumors that have suddenly vanished after being prayed for. Sums of money have appeared, just enough to meet a desperate person’s needs. Souls have been saved. I knew a woman whose heavy alcoholism was just taken from her upon her salvation, with no resultant DT’s. Other substance abusers who became Christians didn’t have all their desires taken from them but had to “twelve step” it, but their’s is ongoing miracle of grace as they carry their crosses for the Lord. Paul didn’t have his thorn taken out of his flesh yet at the same token, God used Paul to perform miracles thru him.
The general sorts of miracles God is doing is a kind of “down here in the trenches, tactical” sort of miracles...every day “day of small things” kind of miracles that often we are dimly aware of at best. Later reflection can bring upon the realization of just what God was doing in “this situation” or “that event” leaving one in a kind of mental...”face palming, self smacking of the head” kind of thankfulness for the grace of God that kept us from flying apart in our darkest moments!
fyi - you brought a year old thread to the surface.
