Day 21: Wrapping Up the Old Testament in Light of the Cross

We wrap up our Old Testament series by looking at how everything comes into focus when we read it in light of Jesus and the cross, like a mystery where the ending makes sense of all the earlier clues. We review sin’s four dimensions from Adam and Eve—breaking God’s command, betraying trust, aligning with and becoming enslaved to the enemy, and forfeiting the good life with God—and how the cross undoes this through justification (substitutionary sacrifice), reconciliation and redemption (restoring what’s been lost), victory over the enemy (seen in Exodus and David), and new life through resurrection. We trace the Old Testament’s repeated pattern that no human hero can fix humanity’s “Adam DNA,” pointing to the need for a new kind of life Jesus brings. Throughout, we emphasize the scarlet thread of grace and end by encouraging ongoing dependence on grace through prayer, concluding with the Lord’s Prayer. 00:00 Old Testament Through the Cross 00:56 Four Dimensions of Sin 02:47 The Cross Undoes the Curse 04:54 Need for New Humanity 06:05 Resurrection New Body 07:24 Scarlet Thread of Grace 09:15 Living by Grace Today 10:22 The Lord's Prayer Closing
