Concluding Romans 11 before a topical summer series, Pastor Brent opens with an example of an elaborate mystery devised in 1861 to thwart an assassination attempt on newly elected President Lincoln. The word “mystery” is used 28 times in the NT (21 by Paul) meaning “unclear things become clear.” He then opens Rom. 11 and unfolds the “Mystery” (vv. 25-27); “Reversal” (vv. 28-32); and “Doxology” (vv. 33-36). Keys to remember: 1) Humility, gratitude, and joy should mark all believers, whether natural branches or ingrafted branches; 2) the Jewish rejection of Jesus was the catalyst by which the nations are now hearing the gospel and are invited (ingrafted) into the family of God! Paul himself went from a hardened zealot of the law to a humble recipient of God’s grace, resulting in the doxology we read in vv. 33-36.
