'Faithful' in the Bible

God is faithful, through whom ye were called into the fellowship of his Son Jesus Christ our Lord.

Here, moreover, it is required in stewards, that a man be found faithful.

For this cause have I sent unto you Timothy, who is my beloved and faithful child in the Lord, who shall put you in remembrance of my ways which are in Christ, even as I teach everywhere in every church.

There hath no temptation taken you but such as man can bear: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation make also the way of escape, that ye may be able to endure it.
