Miracles are and always have been rare events and should never be the reason we believe.

"
22For indeed Jews ask for signs and Greeks search for wisdom;
23but we preach Christ crucified, to Jews a stumbling block and to Gentiles foolishness,"

"3When the wine ran out, the mother of Jesus said to Him, "They have no wine."
4And Jesus said to her, "Woman, what does that have to do with us? My hour has not yet come.""
Yet because of lack of faith he performed those miracles - so that those seeing would believe.
"
11This beginning of His signs Jesus did in Cana of Galilee, and manifested His glory, and His disciples believed in Him."

"
31When Israel saw the great power which the LORD had used against the Egyptians, the people feared the LORD, and they believed in the LORD and in His servant Moses."
But something greater was given to us - faith without miracles. We should not need signs or wonders to believe. Jesus was the fulfillment of prophecy - the last of the great signs to be given. Now we walk by faith and not by sight.

"
24For in hope we have been saved, but hope that is seen is not hope; for who hopes for what he already sees?
25But if we hope for what we do not see, with perseverance we wait eagerly for it."

"
17For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison,
18while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal."
Hope through faith is a greater gift than any miracle you could ever ask to witness. Because even though those miracles were displayed as they trekked through the wilderness - they still lost their hope - precisely because they could see. They once again fell to worshiping what they could see and touch and lost the hope they had.
Miracles may be worked in an individuals life, but expect to see none in the world at large. For the next great working of miracles to the world will be by one who comes to deceive the whole world - simply by giving them what they ask for - signs and wonders, and they will fall down before the feet of the wicked one and be lost forever - deceived by those very miracles they need to believe.

"
8Then that lawless one will be revealed whom the Lord will slay with the breath of His mouth and bring to an end by the appearance of His coming;
9that is, the one whose coming is in accord with the activity of Satan, with all power and signs and false wonders,
10and with all the deception of wickedness for those who perish, because they did not receive the love of the truth so as to be saved.…"
