Christians,miracles happen all the time, so why...?

Life should've shown you by now that God works in mysterious ways, and usually something you find a hinderance ends up being a blessing in disguise.

God produced a whole woman from just a rib (Genesis 2:22) ... Jesus repaired an amputated ear (Luke 22:49-50)

That's two ... and a specific example of a healed amputation.

By the way, speaking only of the Bible, I don't believe that people survived arm or leg amputations over 2000 years ago. They bled to death. So, I would guess this is the reason that there are not individuals in the Bible that are described as being without arms or legs, and (as a result) there wouldn't be an opportunity for an armless man to walk up to Jesus and request healing.

You are right that miracles happen everyday and probably one of the reasons you don't hear or see about the amputees leg being restored is because God heals it long before it gets to that point, like you said the crippled walk. I am sure God has done this many times we just have not heard about or believed it when it happened. These miracles have a spiritual meaning too. The blind seeing also means that they come to the realization that Jesus Christ died for them on the Cross at Calvery. Think about it, whenever you see a cross does it remind you of Jesus? For most people it does and it is a reminder God put in our hearts that His Son gave his life to save ours. Jesus's perfect sacrifice at the Cross opens the door to salvation to all who will believe, to all who will confess their sins and call him Saviour and Lord. You can do so right now, if you believe, just pray this simple sinners prayer and a new life will be yours if you choose Christ, Dear Jesus, I know and confess that I am sinner in need of salvation. I believe you died on a cross at calvery and arose from the grave to wash away my sins, I ask you right now to come into my heart and save me, I pray this Prayer believing in the name of Jesus Amen. If you prayed this prayer with a sincere heart you are now a child of God, rejoice that your name is written in the Lambs book of Life. Jesus will now send his Holy Spirit to come and live in your heart and guide you into all truth. If you have any questions just send me an email, God Bless YOU!!

Cause actually there are no miracles, people are cure because a lot of reasons, their positive mind also can cure them, taking medications also can do that, and a lot of other reasons, so there are no prove that there are miracles from god.....

I think your looking for reasons not to believe and it is always the christians fault. don't look to us for your answers, pray and ask God himself. If you think you'll make heaven ask Him yourself.
