There are two sides to this:

1) There ARE miracles today, but they are farther apart (in both time and geography) than what we read in scripture. We may just not be in tune with everything that's happening.

2) We wish there are more. There are very real situations today that are in need of miracles, but as believers we have to trust God's will. We know He's in control, but we are called to first long for the will of God, not to see evidence or signs.
