What are we to make of Jacob wrestling with God in Genesis 32? Jacob cried, "I won't let you go until you bless me!" A traditional revivalist/pietist piece of exegesis would go, "We must wrestle with God in prayer until we sense some kind of blessing." But that reading is a derivative application at best and it cuts Christ out of the picture.
Jacob is a type of Christ, who "strives" with God for His blessing, or for the joy set before him according to Hebrews 12:2. Jacob 'sees' God's face (32:30 - probably that of the pre-incarnate Christ), whereas only Christ has seen God's face (John 1:18). Like Jacob, Christ comes away injured after his procuring the blessing. Jacob's side was injured whilst Christ's was pierced. The people of Israel, out of reverence for Jacob's encounter "do not eat the tendon attached to the socket of the hip." (v32) In contrast, the New Israel, in response to Christ's crucifixion, feed on his body and blood (John 6:55).
How should we respond? By realising that Christ has done it all; that he fulfilled the law's demands. All that is left for us to do, is to bask in the glory of the blessing he procured. We bask by feeding on him through the word preached and the sacraments received. We no longer strive for the blessing. Gospel righteousness isn't something to be wrestled down from heaven, or dug up from the grave; rather it's as near as the Christ we confess (Romans 10:5-12). And resting on his accomplishments is the impetus we need as we strive to make every effort to add to our faith all kinds of evangelical virtues (2 Peter 1:5).
