Whatever is born of God overcomes the world. And this is the victory that has overcome the world -- our faith. (1 John 5:4)

Now faith is the substance of things hoped for, the evidence of things not seen. (Hebrews 11:1)

So Jesus answered and said to them, "Have faith in God. For assuredly, I say to you, whoever says to this mountain, 'Be removed and be cast into the sea,' and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says. Therefore I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them." (Mark 11:22-24)

But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a re-warder of those who diligently seek Him. (Hebrews 11:6)

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

That the genuineness of your faith, being much more precious than gold that perishes, though it is tested by fire, may be found to praise, honor and glory at the revelation of Jesus Christ, whom having not seen you love. Though now you do not see Him, yet believing, you rejoice with joy inexpressible and full of glory, receiving the end of your faith -- the salvation of your souls. (1 Peter 1:7-9)

So then faith comes by hearing, and hearing by the word of God. (Romans 10:17)

A women who had a flow of blood for twelve years came from behind and touched the hem of His garment. For she said to herself, "If only I may touch His garment, I shall be made well." But Jesus turned around, and when He saw her He said, "Be of good cheer, daughter; your faith has made you well." And the woman was made well from that hour. (Matthew 9:20-22)

When He had come into the house, the blind men came to Him. And Jesus said to them, "Do you believe that I am able to do this?" They said to Him, "Yes, Lord." Then He touched their eyes, saying, according to your faith let it be to you." (Matthew 9:28, 29)

Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith will save the sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven. (James 5:14, 15)
