Christ isn’t some weakling who is just waiting for people to repent while he bites his nails hoping they do. Paul says that Christ must reign until all his enemies are made his footstool (1 Cor 15:25). We see a war waged against the Lamb and he personally conquers over his enemies because of who he is (Rev 17:14). The book of Revelation is filled with horrifying images, but how powerful and horrifying is the image of Christ, on a horse, slaying his enemies like grapes in a winepress, their blood filling a valley several miles wide so that his horse has to wade through it (Isaiah 63:3; Rev 14:14-20;19:11-16)?
Jesus is no weakling King.
He is a King who has authority right now, and will enforce that authority on a later date. Gentiles will continue to flock to him and eventually sit beneath his banner (Is 11:10) while the Jews realize their error and flock to him (Ho 3:5) and ultimately all his handed over to God (1 Cor 15:28).
When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.
And it is in this context that Paul thinks about Adam: the King who failed and didn’t conquer. Adam couldn’t even rule over his own home and winds up having creation rule over him.
Jesus is a King who conquers.
