Some may argue that miracles don't happen in our time, that the era of Spiritual Gifts ended with the Apostles. I don't agree. I believe that miracles are happening all around us, or could, but because we have lost sight as to the purpose of miracles, they don't. Like I said earlier, I think the purpose of miracles is to bring about God's glory. It is our fault if we don't recognize a miracle and attribute it to God.
Jesus himself was only able to perform miracles if the people had faith in him.
And great crowds came to him, bringing with them the lame, the blind, the crippled, the mute, and many others, and they put them at his feet, and he healed them, so that the crowd wondered, when they saw the mute speaking, the crippled healthy, the lame walking, and the blind seeing. And they glorified the God of Israel. (Matthew 15:30, 31 ESV)
Same with the Apostles.
The miracles brought about the glorification of God's name and nature. It was a healing just for the sake of healing; miracles were performed with a kingdom purpose. I think we could all use a little more faith and prayer that miracles will occur to further the Kingdom.
