There is a saving and a living faith!
Hebrews 11:1, 6 (NKJV)
1 Now faith is the substance of things hoped for, the evidence of things not seen.
6 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 rewarder of those who diligently seek Him.
Matthew 17:20-21 (NKJV)
20 So Jesus said to them, "Because of your unbelief; for assuredly, I say to you, if you have faith as a mustard seed, you will say to this mountain, 'Move from here to there,' and it will move; and nothing will be impossible for you.
21 However, this kind does not go out except by prayer and fasting."
Romans 10:17 (NKJV)
17 So then faith comes by hearing, and hearing by the word of God.
Galatians 3:11 (NKJV)
11 But that no one is justified by the law in the sight of God is evident, for "the just shall live by faith."
