Thus 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.
1 Corinthians 1:9God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord.
1 Thessalonians 5:24Faithful is he that calleth you, who also will do it.
