Outside perception which is natural and cast in the human image is an all inclusive world that I as a Christian would call as kingdom of heaven. Different sets of rules work in each world that is permitted but not accepted for ever. In the age of grace we need to realize serving God is the door to Kingdom of God and serving Mammon is a trip along the broadway to destruction.
Miracles must be explained as blessings flowing from the greater to the lesser.
In the midst of winter my wife and I packed peanuts along the branches in our front garden for birds to peck at. (It is like food reserves stashed in the Arctic regions for Arctic explorers to help themselves in need.) I wanted to observe myself how many kinds of birds would pass their way through. Sure enough the birds came down flapping their wings to gorge on the precious food. It struck me that they must be thinking it a miracle to find peanuts spouting from birch saplings! I know where these peanuts come from and how much the local garden center charges for each. For the birds not having this knowledge the sight must seem incredible.
In the gospel of St. Matthew we read of a miracle of Jesus. In his earthly ministry he found himself in a desert place. It was late for the crowd who had come to hear Jesus speak find a place to find food. The disciples found the crowd was great that they had no means to provide food for all. Unconcerned their fumbling Jesus said, ’Give ye them food to eat.’ They exercised their reason, ’Shall we go and buy two hundred penny worth of bread?‘ They knew the cost of food but not what Jesus could do. It was for Jesus nothing extraordinary. Five loaves and two fishes he multiplied so each could be fed and there was still left over. Jesus had the means to feed them and also knew when. A miracle was possible because the kingdom of heaven and kingdom of men overlapped when Jesus walked the earth.
Before the Passion Jesus told Peter:’ whatsoever thou shalt bind on earth shall be bound…’(Mt.16:19) Since Jesus has opened up a way miracles do occur where a need exists and one takes responsible as a servant of the kingdom of heaven. In the Old Testament miracles that Elisha and Elijah performed were as prophets from the Kingdom of God.
To sum: miracles as we perceive them on earth is but a trifle for those who inhabit the kingdom above. Raising Lazarus from death was a miracle but I do not assume that did give him immortality. Lazarus of Bethany would have died like every other. It was an exercise in faith and Jesus worked a miracle for the benefit of others demonstrating his own approaching death and the resurrective power that would lift him to his Father. Jesus truly loved the dead man and it connected his own death and the life after death through Lazarus for all mankind. A miracle that increases the faith of a believer is a means to turn him towards the world beyond.
