Then Jesus was led by the Spirit into the wilderness to be tempted by the devil. 2 After fasting forty days and forty nights, he was hungry. 3 The tempter came to him and said, “If you are the Son of God, tell these stones to become bread.” 4 Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.’” 5 Then the devil took him to the holy city and had him stand on the highest point of the temple. 6 “If you are the Son of God,” he said, “throw yourself down. For it is written: “‘He will command his angels concerning you, and they will lift you up in their hands, so that you will not strike your foot against a stone.’” 7 Jesus answered him, “It is also written: ‘Do not put the Lord your God to the test.’” 8 Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. 9 “All this I will give you,” he said, “if you will bow down and worship me.” 10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’” 11 Then the devil left him, and angels came and attended him. Matthew 4:1-11 (NIV)

28 And when He had come into the house, His disciples asked Him privately, “Why could we not cast it out?” 29 So He said to them, “This kind can come out by nothing but prayer and fasting.” Mark 9:28-29 (NKJV) 

23 Jesus said to him, “If you can believe, all things are possible to him who believes.” Mark 9:23 (NKJV)

20 Now to Him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, Ephesians 3:20 (NKJV)
