Matthew 25:31-46 KJV
[31] When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: [32] And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats: [33] And he shall set the sheep on his right hand, but the goats on the left. [34] Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: [35] For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: [36] Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. [37] Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink? [38] When saw we thee a stranger, and took thee in? or naked, and clothed thee? [39] Or when saw we thee sick, or in prison, and came unto thee? [40] And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me. [41] Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: [42] For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink: [43] I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not. [44] Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee? [45] Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me. [46] And these shall go away into everlasting punishment: but the righteous into life eternal.

John 6:29 KJV
[29] Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.

2 Thessalonians 3:2 KJV
[2] And that we may be delivered from unreasonable and wicked men: for all men have not faith.

Hebrews 11:5-6 KJV
[5] By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God. [6] But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.

James 2:14-26 KJV
[14] What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him? [15] If a brother or sister be naked, and destitute of daily food, [16] And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit? [17] Even so faith, if it hath not works, is dead, being alone. [18] Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works. [19] Thou believest that there is one God; thou doest well: the devils also believe, and tremble. [20] But wilt thou know, O vain man, that faith without works is dead? [21] Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? [22] Seest thou how faith wrought with his works, and by works was faith made perfect? [23] And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God. [24] Ye see then how that by works a man is justified, and not by faith only. [25] Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent them out another way? [26] For as the body without the spirit is dead, so faith without works is dead also.

1 John 3:23 KJV
[23] And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.

2 Thessalonians 3:2 KJV
[2] And that we may be delivered from unreasonable and wicked men: for all men have not faith.
