1. To speak only of him as he is mediator: he was authorized to this blessed work by his Father, before the world began. Hence the apostle saith, "He hath chosen us in him before the foundation of the world" (Eph 1:4). With all those things that effectually will produce our salvation. Read the same chapter, with 2 Timothy 1:9.
2. He was promised to our first parents, that he should, in the fullness of time, bruise the serpent's head; and, as Paul expounds it, redeem them that were under the law. Hence, since that time, he hath been reckoned as slain for our sins. By which means all the fathers under the first testament were secured from the wrath to come; hence he is called, "The Lamb slain from the foundation of the world" (Rev 13:8; Gen 3:15; Gal 4:4,5).
3. Moses gave testimony of him by the types and shadows, and bloody sacrifices, that he commanded from the mouth of God to be in use for the support of his people's faith, until the time of reformation; which was the time of this Jesus his death (Heb 9, 10).
4. At the time of his birth it was testified of him by the angel, "That he should save his people from their sins" (Matt 1:21).
5. It is testified of him in the days of his flesh, that he had power on earth to forgive sins (Mark 2:5-12).
6. It is testified also of him by the apostle Peter, that "God hath exalted him with his own right hand, to be a prince and a Saviour, for to give repentance to Israel, and forgiveness of sins" (Acts 5:31).
7. In a word, this is everywhere testified of him, both in the Old Testament and the New. And good reason that he should be acknowledged and trusted in, as a Saviour.
(1.) He came down from heaven to be a Saviour (John 6:38-40).
(2.) He was anointed when on earth to be a Saviour (Luke 3:22).
(3.) He did the works of a Saviour. As, (a.) He fulfilled the law, and became the end of it for righteousness, for them that believe in him (Rom 10:3,4). (b.) He laid down his life as a Saviour; he gave his life as "a ransom for many" (Matt 20:28; Mark 10:45; 1 Tim 2:6). (c.) He hath abolished death, destroyed the devil, put away sin, got the keys of hell and death, is ascended into heaven; is there accepted of God, and bid sit at the right hand as a Saviour; and that because his sacrifice for sins pleased God (2 Tim 1:10; Heb 2:14,15; 10:12,13; Eph 4:7,8; John 16:10,11; Acts 5:30,31).
