“It is obvious that the reason they do not believe/come is because the Father has not ‘given’ them to Jesus. So although they had seen all his miracles they were unable to be saved because God the Father did not allow them to come/ believe in Jesus- they were unregenerate.”

I understand that this was Calvin’s view on the elect. However, I cannot find any place in Scripture where God does not allow someone who desires to come to Him, to come to Him. To believe such sounds very much like God is a preferer of persons and prejudiced like the rest of humanity. But God’s ways are not like our ways, they are superior in reason and in divine compassion.
