Chapter Eight of the Westminster Confession of Faith contains a valuable summary of the person and work of Jesus Christ. If you want to know who Jesus is, familiarize yourself with what the Puritans compiled in the Westminster Confession of Faith.
I will reproduce the content from the Confession, followed by its biblical foundation. There are eight sections concerning Jesus Christ. We will share a section each day for eight days. Enjoy!
Section III is as follows. It will be identified as (1) Confessional Statement followed by its (2) Biblical Foundation.
The Lord Jesus, in His human nature thus united to the divine, was sanctified, and anointed with the Holy Spirit, above measure, having in Him all the treasures of wisdom and knowledge; in whom it pleased the Father that all fullness should dwell; to the end that, being holy, harmless, undefiled, and full of grace and truth, He might be thoroughly furnished to execute the office of a Mediator and Surety. Which office He took not unto Himself, but was thereunto called by His Father,  who put all power and judgment into His hand, and gave Him commandment to execute the same.
 PSALM 45:7 Thou lovest righteousness, and hatest wickedness: therefore God, thy God, hath anointed thee with the oil of gladness above thy fellows. JOHN 3:34 For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him.
 COLOSSIANS 2:3 In whom are hid all the treasures of wisdom and knowledge.
 COLOSSIANS 1:19 For it pleased the Father that in him should all fullness dwell.
 HEBREWS 7:26 For such a high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens. JOHN 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
 ACTS 10:38 How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him. HEB 12:24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel. HEBREWS 7:22 By so much was Jesus made a surety of a better testament.
 HEBREWS 5:4 And no man taketh this honour unto himself, but he that is called of God, as was Aaron. 5 So also Christ glorified not himself to be made a high priest; but he that said unto him, Thou art my Son, today have I begotten thee.
 JOHN 5:22 For the Father judgeth no man, but hath committed all judgment unto the Son. 27 And hath given him authority to execute judgment also, because he is the Son of man. MATTHEW 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. ACTS 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
This is who Jesus is. Soli deo Gloria!
