[4.] They being given unto him, he undertaking for them to do and suffer what was on their part required, he received, on their behalf and for them, all the promises of all the mercies, grace, good things, and privileges, which they were to receive upon the account of his undertaking for them. On this account eternal life is said to be promised of God “before the world began,” Tit. i. 2; that is, to the Son of God for us, on his undertaking on our behalf. And grace, also, is said to be given unto us “before the world began,” 2 Tim. i. 9; that is, in Christ, our appointed head, mediator, and representative.
