Ephesians says God made known “the mystery of his will” as a plan for the fullness of time. The plan is “to unite all things in him,” things in heaven and things on earth. See Ephesians 1:9–10.
In Ephesians 1:7–10, Paul says that “in” Christ the community already has redemption, described as forgiveness, and that this comes from God’s overflowing generosity. God’s generosity is not random; it is marked by wisdom and purposeful direction. These verses sit inside the long opening blessing that runs from 1:3 onward, where Paul lists reasons to praise God and traces a coherent storyline of God’s action. The passage builds on the earlier emphasis that blessings are found “in Christ” and now names a central benefit: redemption/forgiveness.
Ephesians 1:7–10 presents redemption as something the community already has in Christ. The text ties redemption directly to “through his blood” and explains it as “forgiveness of our trespasses.” The scale of this gift is not measured by human worth but by “the riches of his grace,” which God makes “abound” toward the recipients.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Ephesians 1:9-10, then read the surrounding section so the answer stays connected to the passage's flow.
