Kids playing musical instruments is hilarious. First off, there is the excitement of the new adventure. This lasts as long as the time between receiving the instrument and the first time you ask them: Did you practice? Then comes the utter shock of the first rehearsal. You become a ball of nerves for the recital and the show is amazing. The Gospel is much like playing an instrument.
As we read 1 Timothy 6:13-16, Paul rehashes the story of the Gospel. As he instructed Timothy to pursue certain things, he demonstrates how this looked in the action of Jesus. There is a fundamental need to state the obvious and reshape the Gospel as we grow in our faith. This is not an insult to intelligence, but a core feature to mimicking the actions and life of Jesus.
As the Gospel was practiced with Timothy, there was no doubt the rehearsal to the church Timothy was in charge of. Often the letters written by Apostles were read allowed in a gathering. While we practice our part, rehearsal helps us to see how the whole team works together to accomplish the mission.
Paul makes clear that Jesus will be back. And the event will be absolutely amazing. Paul in another letter describes how every knee will bow and every tongue confess that Jesus is Lord to the glory of God the father. Meaning? While life is hard and not fair currently, there is a moment, the concert moment if your will, where things all make sense and we fully realize who Jesus is and the impact of the Gospel.
