TO give effect to His eternal purpose God chose and ordained the Lord Jesus, His only begotten Son, in accordance with the covenant into which they had entered, to be the mediator between God and man; also to be prophet, priest, king, head and savior of His church; also to be the heir of all things and judge of the world. From all eternity God had given to His Son those who were to be His progeny, and the Son engaged in time (as distinct from eternity) to redeem, call, justify, sanctify, and glorify them.

Ps. 2:6; Isa. 42:1, 53:10; Luke 1:33; John 17:6; Acts 3:22, 17:31; Rom. 8:30; Eph. 1:22-23; Heb. 1:2, 5:5-6; 1Pet. 1:19-20.

The divine Person who made the world, and upholds and governs all things that He has made, is the Son of God, the second Person of the Holy Trinity.He is true and eternal God, the 'brightness of the Father's glory', of the same substance (or essence) as the Father, and equal with Him. It is He who, at the appointed time, took upon Himself the nature of man, with all its essential characteristics and its common infirmities, sin excepted. He was conceived by the Holy Spirit in the womb of the Virgin Mary, a woman who belonged to the tribe of Judah, the Holy Spirit coming down upon her and the power of God most High overshadowing her. And so, as the Scripture tells us, He was made of a woman, a descendant of Abraham and David. In this way it came about that the two whole, perfect, and distinct natures, the divine and the human, were inseparably joined together in one Person, without the conversion of the one nature into the other, and without the mixing, as it were, of one nature with the other; in other words, without confusion. Thus the Son of God is now both true God and true man, yet one Christ, the only mediator between God and man.

Matt. 1:22,23; Luke 1:27,31,35; John 1:14; Rom. 8:3; 9:5; Gal. 4:4; 1 Tim. 2:5; Heb. 2:14,16,17; 4:15.

The two natures, divine and human, being thus united in the person of God's Son, He was sanctified and anointed with the Holy Spirit to an unlimited extent, and in Him are found all treasures of wisdom and knowledge. He is replete with all that is pleasing to the Father, being holy, harmless, untouched by sin, and full of grace and truth.Thus He has become thoroughly qualified to execute the work of a mediator and surety. He did not take this work upon Himself uncalled, but was commissioned by His Father so to act. His Father also conferred upon Him full powers of jurisdiction and commanded Him to pass judgment on all.

Ps. 45:7; Matt. 28:18; John 1:14; 3:34; 5:22,27; Acts 2:36; 10:38; Col. 1:19; 2:3; Heb. 5:5; 7:22,26.

The Lord Jesus most willingly undertook the office of mediator, and in order that He might discharge it He became subject to God's law, which He perfectly fulfilled. He also underwent the punishment due to us, which we should have borne and suffered, for He bore our sins and was accursed for our sakes. He endured sorrows in His soul severe beyond our conception, and most painful sufferings in His body. His death was, by crucifixion. While He remained in the state of the dead His body sustained no decay. The third day saw His resurrection in the same body in which He had suffered. In the same body also He ascended into heaven, where He sits at the right hand of His Father, interceding for His own. At the end of the world He will return to judge men and angels.

Ps. 40:7-8; Isa. 53:6; Matt. 3:15, 26:37-38, 27:46; Mark 16:19; Luke 22:44; John 10:18, 20:25, 20:27; Acts 1:9-11; 10:42; 13:37; Rom. 8:34; 14:9-10; 1Cor. 15:3,4; 2Cor. 5:21; Gal. 3:13; 4:4; Heb. 9:24; 10:5-10; 1Pet. 3:18; 2Pet. 2:4.

By His perfect obedience to God's law, and by a once-for-all offering up of Himself to God as a sacrifice through the eternal Spirit, the Lord Jesus has fully satisfied all the claims of divine justice. He has brought about reconciliation, and purchased an everlasting inheritance in the kingdom of heaven, for all those given to Him by His Father.

John 17:2; Rom. 3:25,26; Heb. 9:14,15.

The price of redemption was not actually paid by Christ until after His birth in this world, but the value, efficacy and benefits of His redemptive work availed for His elect in all ages successively from the beginning of the world. This was accomplished by the promises, the types and the sacrifices in which He was revealed, and which signified Him to be the woman's 'seed' (offspring) who should bruise the head of the serpent (the devil), also 'the Lamb slain from the foundation of the world'. As the Christ He is 'the same yesterday, and today, and for ever'.

1 Cor. 4:10; Heb. 4:2; 13:8; 1 Pet. 1:10,11; Rev. 13:8.

In His work as mediator between God and men, Christ acts according to His two natures, one divine, one human, in each nature doing that which is appropriate to it.Yet by reason of the unity of His Person, that which is appropriate to one nature is, in Scripture, sometimes attributed to the Person denominated by the other nature.

John 3:13; Acts 20:28.

Christ certainly and effectually applies and communicates eternal redemption to all those for whom He has obtained it. His work of intercession is on their behalf. He unites them to Himself by His Spirit; He reveals to them, in and by the Word, the mystery of salvation; He persuades them to believe and obey, governing their hearts by His Word and Spirit; He overcomes all their enemies by His almighty power and wisdom, using those methods and ways which are most agreeable to the wonderful and unsearchable appointments of His providence. All these things are carried out in His free and sovereign grace, and unconditionally, nothing of merit being foreseen by Him in the elect.

Ps. 110:1; John 3:8; 6:37; 10:15,16; 17:6,9; Rom. 5:10; 8:9,14; 1 Cor. 15:25,26; Eph. 1:8,9; 1 John 5:20.

Christ, and Christ alone, is fitted to be mediator between God and man. He is the prophet, priest and king of the church of God. His office as mediator cannot be transferred from Him to any other, either in whole or in part.

1 Tim. 2:5.

Christ's threefold offices are necessary for us. Because of our ignorance we stand in need of His prophetical office; because of our estrangement from God and the imperfection of our services at their best, we need His priestly office to reconcile us to God and render us acceptable to Him; because we have turned away from God and are utterly unable to return to Him, and also because we need to be rescued and rendered secure from our spiritual adversaries, we need His kingly office to convince, subdue, draw, sustain, deliver and preserve us, until we finally enter His heavenly kingdom.

Ps. 110:3; Luke 1:74,75; John 1:18; 16:8; Gal. 5:17; Col. 1:21.
