Samsons Defeats Thousands (Judges 15: 15-16)
One of the most impressive miracles to me is one that involved Samson. However, this is not the traditional one when he destroy the city. To believe that he was given the ability defeat 1000 men with a mere bone is almost unbelievable. To stand infront of 1000 men with the confidence that God will allow you defeat your enemies shows faith and understanding.  In addition, earlier in the chapter Samson also caught 300 foxes. (Can you imagine just catching 1?)
 
Passages
 
15And he found a new jawbone of an ass, and put forth his hand, and took it, and slew a thousand men therewith.
 16And Samson said, With the jawbone of an ass, heaps upon heaps, with the jaw of an ass have I slain a thousand men.
 
Jesus Fasting for 40 Days and 40 Nights (Matthew 4)
Some persons may not see this as a miracle (since it was Jesus) but I certainly do. This shows us that the gifts of heavens are far greater than the pleasures of this earth. Jesus was continually tempted by the devil on 3 different levels (Hungry, Pride, Riches & Power). 
Consequently, to believe that Jesus (a man) walked in the wilderness for 40 days and nights and ate nothing is absolute incredible.  40 hours without food for me is way too but 40 days, WOW. 
 
Peter Walking On Water (Matthew 14)
I dont think I really need say anything about this miracle as it goes against everything we learnt in Science class. But this would be expected from the God who create science.
However, there is one thing that I believe I need to say.  As Peter lost faith in Jesus he began to sink, this shows us that only through true faith that these mircales can happen.  
 
Peter Walking Out Of Prison (Acts 12)
This is my favourite miracle so far with my reading of the bible.  So many unbelievable, amazing and incredible things happened to allow Peter to walk out of prison. The angel came and the chains fell off his hands then he walked straight past the guards. The massive gates opened when he walked infront of them in addition, he was ability to walk safely to a safe house with follow believers. Truly Amazing. 
Passages
 
7And, behold, the angel of the Lord came upon him, and a light shined in the prison: and he smote Peter on the side, and raised him up, saying, Arise up quickly. And his chains fell off from his hands.
 8And the angel said unto him, Gird thyself, and bind on thy sandals. And so he did. And he saith unto him, Cast thy garment about thee, and follow me.
 9And he went out, and followed him; and wist not that it was true which was done by the angel; but thought he saw a vision.
 10When they were past the first and the second ward, they came unto the iron gate that leadeth unto the city; which opened to them of his own accord: and they went out, and passed on through one street; and forthwith the angel departed from him.
 
 
Sadrach, Meshach and Abednego (Daniel 3)
As Radiant, put it in her study answer, this shows what God can do for you and when you follow him.
