Who verily was fore-ordained; by God's decree appointed to the work of redemption, and to be that Lamb that should take away the sins of the world, Ephesians 1:9. Before the foundation of the world; from eternity; there being nothing before the world began but what was eternal, 1 Thessalonians 17:24. But was manifested; not only by his incarnation, 1 Timothy 3:16, but by the preaching of the gospel. See these Scriptures: Galatians 4:4 Ephesians 1:10 Hebrews 1:2, Hebrews 9:26. In these last times; last, in comparison of the times of the Old Testament; the same as the fulness of time, Galatians 4:4. For you; that you, with other believers, might partake of salvation by him. The fruit of Christ's redemption reacheth all ages, but much more abundantly the times after his coming in the flesh. The sum of the argument is, Christ was ordained from eternity, promised to the fathers, but manifested to you: your privilege therefore being greater than theirs, Matthew 13:17 Hebrews 11:39,40, you should be the more holy.
