The disciples had been puzzled. Is attaining Heaven so difficult? Specific categories were mentioned: adulterers (incl. divorced persons) - eunuchs - murderers - thieves - perjurers - rebels & derelicts - those having great possessions - no Heaven for any of them.
Matthew 19:25-26 When his disciples heard it, they were exceedingly amazed, saying, Who then can be saved? But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible.
With God all things are possible. Sometimes it's difficult to grasp what that means. The disciples must have read (or at least heard of) God's commandments and Jesus had cited Moses so
someone must have known who he was. The point was that although by their own efforts, divorcées or murderers and others like that could never attain Salvation, for God the impossible is reality. Even degenerate heathens (and degenerate they must be since had they retained God in their knowledge throughout their descent from Adam, they would not be heathens) may be Saved.
Nowadays there's an agenda to establish secular values and offer alternative explanations for what God has revealed. They are strangely inconsistent. On the one hand, Jesus never existed (or if He did but not as described then all we're left with is that "Jesus" is a name which was never in dispute anyway) whereas on the other, He performed miracles which have naturalistic explanations such as post-mortem appearances caused by grief, separation anxiety and group hallucinations. Take your pick.
But always make it as complicated as possible.
My earlier map seems to have flown off into the aether but could do with updating so I'll fix that in asking, "How do you explain Philip's experience? Teleportation? Serendipitous wormhole? Hyperspace?" He had gone from Samaria to the Jerusalem-Gaza road, then spontaneously relocated to Azotus. Let's go with serendipitous wormhole. Its (internal) length is indeterminate, ok, but the distance to traverse in our mundane reality is fixed. Depending on how far along the road the Ethiopian had got, there is a maximum range.
Here is the map –›
They rode along, away from Jerusalem, as Philip explained why Jesus needed to die or more specifically why His blood needed to be drained out and dribble down onto the dirt. That can't happen without death occurring. So Jesus died. And since He was alive during all this He died horribly, jabbed with a spear, agony, despairing and all alone. He said so.
If they'd gotten along 4 miles from Jerusalem, it would be a 20 mile translation to Azotus; the miles from Jerusalem are shown along the road and the distance to Azotus next to the town. The Bible is clear that Philip did not walk there but if he had, you can guess the time it would take from the distance.
And this is where the false paradigm of secularism comes unstuck. Without a serendipitous wormhole opening up under Philip's feet as he jumped down from the chariot, what have they got? Maybe the Ethiopian sold him a teleporting device! Or what about, the chariot had hyperspace capabilities?
For mere humans such things are impossible. But as Matthew recorded, with God all things are possible. Even for the Lost to be Saved.
