Faithful

Concise Bible Dictionary:

This word in both the O. T. and the N. T. is from the same root as “faith.” It is being true to oneself, to one's nature, to any promise given, and to any trust committed. It is in various connections often applied to God Himself (Deut. 7:99Know therefore that the Lord thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations; (Deuteronomy 7:9); Isa. 49:77Thus saith the Lord, the Redeemer of Israel, and his Holy One, to him whom man despiseth, to him whom the nation abhorreth, to a servant of rulers, Kings shall see and arise, princes also shall worship, because of the Lord that is faithful, and the Holy One of Israel, and he shall choose thee. (Isaiah 49:7); 1 Cor. 1:99God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord. (1 Corinthians 1:9); 1 Cor. 10:1313There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it. (1 Corinthians 10:13); 1 Thess. 5:2424Faithful is he that calleth you, who also will do it. (1 Thessalonians 5:24); 2 Tim. 2:1313If we believe not, yet he abideth faithful: he cannot deny himself. (2 Timothy 2:13); Heb. 10:2323Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) (Hebrews 10:23); 1 Pet. 4:1919Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator. (1 Peter 4:19); 1 John 1:99If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. (1 John 1:9)). The Lord Jesus also is faithful. He is “a faithful high priest” and a “faithful and true witness” (2 Thess. 3:33But the Lord is faithful, who shall stablish you, and keep you from evil. (2 Thessalonians 3:3); Heb. 2:1717Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people. (Hebrews 2:17); Rev. 1:55And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood, (Revelation 1:5); Rev. 3:1414And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God; (Revelation 3:14); Rev. 19:1111And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. (Revelation 19:11)). The commandments and testimonies of God are called faithful (Psa. 119:86, 13886All thy commandments are faithful: they persecute me wrongfully; help thou me. (Psalm 119:86)
138Thy testimonies that thou hast commanded are righteous and very faithful. (Psalm 119:138)). The words of the gospel are also faithful: the promises attached thereto will unquestionably be fulfilled (1 Tim. 1:1515This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief. (1 Timothy 1:15); 1 Tim. 4:99This is a faithful saying and worthy of all acceptation. (1 Timothy 4:9); 2 Tim. 2:1111It is a faithful saying: For if we be dead with him, we shall also live with him: (2 Timothy 2:11); Titus 3:88This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men. (Titus 3:8); Rev. 21:55And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful. (Revelation 21:5)). Christians are exhorted to be faithful as stewards to any trust committed to them, and faithful as witnesses to an absent Lord. "Be thou faithful unto death, and I will give thee a crown of life" (Rev. 2:1010Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life. (Revelation 2:10)).
