I think it's obvious that miraculous healings have ended. There hasn't been anyone since the first century who can immediately heal the sick, give sight to the blind, make the lame walk, or raise the dead.
Apostles are men that have the power to perform miracles. The twelve disciples were given this power. So was Paul. James (the Lord's brother), Barnabas, Andronicus, Junias are referred to as apostles. This is what the Bible says:
(2 Corinthians 12:12 NIV) The things that mark an apostle--signs, wonders and miracles--were done among you with great perseverance.
There is some anecdotal evidence to suggest that miraculous healings occur today in third world countries that are just now being reached with the gospel. People are healed after Christians pray for them. God uses that to give authenticity to the gospel.
Interesting.
But to me, strictly looking at the what the Bible says about the matter, I don't see anywhere that says miraculous signs can't happen today or don't happen today. I have never seen one. Many teach that they don't happen anymore because the Bible says they won't but I am not convinced either way.
