In Eph 3, the Apostle Paul describes the wonder of God’s grace in commissioning him to take the Gospel to the Gentiles. Paul felt unworthy, referring to himself as the least of all the saints. Yet, by God’s grace, he was given the task of preaching the unsearchable riches of Christ to the Gentiles. Paul had been describing these unsearchable riches from the very beginning of the epistle. When reading the first two chapters in this light, those riches flow one after another like a cascading waterfall of grace.
