So Jesus said to them, '...for assuredly, I say to you, if you have faith as a mustard seed, you will say to this mountain, Move from there to there, and it will move: and nothing will be impossible for you'
So then faith comes by hearing, and hearing by the Word of God
That whoever believes in Him should not perish, but have eternal life
Therefore having been justified by faith, we have peace with God through our Lord Jesus Christ
1 Corinthians 12:9
To another faith [is given] by the same Spirit...
...knowing that a man is not justified by the works of the law, but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ, and not by the works of the law; for by the works of the law no flesh shall be justified
