Miracles
I have seen magicians do tricks which look like miracles to me.
However, magicians don't seem to require me to believe anything.
The Israelites leaving Egypt saw the 10 plagues fall on Egypt, walked through the parted Red Sea, witnessed the daily provision of manna for 40 years - every day except the Sabbath. Yet they were a dead loss.
Christ criticised some of the Israelite cities He did miracles in saying in Matthew 11:21 Woe unto thee, Chorazin! woe unto thee, Bethsaida! for if the mighty works, which were done in you, had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes.
At the end of Christ's miracle-working ministry, He seemed to be left with 11 disciples, a few women supporters and about five hundred true followers, to whom He appeared after His resurrection. (1 Cor 15:6)
Miracles, per se are fairly useless at generating worthwhile believers.
If there is no faith to view the miracles with, miracles have zero value. The Pharisees saw the miracles Jesus did and ascribed these to Satan.
Christianity took off when the miracles had largely stopped.
The whole book of Acts tells about the spread of Christianity and it is driven by one thing, the Holy Spirit WITHIN the believer. There is no outward manifestation of this in the sense that believers can be known and judged by their miracle-working power.
It is God's express purpose that Christianity is NOT miracle driven. If Christianity was miracle-driven, then no faith would be required.
The Antichrist who will arise before the end will "prove" his credentials as a "man of God" by producing miracles such as have not been seen since Christ.
2 Thes 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
So, God grants to His opposition supernatural power to perform miracles to lure people, including believers, away from Him.
So God's team gets to play The Final with legs shackled, against Team Satan on steroids.
Any ideas why?
