ANSWER: We glorify God by enjoying him, loving him, trusting him, and by obeying his will, commands, and law.
The answer to this catechism question begins with a curious idea: the enjoyment of God. What do you think this means? Can we see anyone enjoying God in Luke Luke 10:38-42?*
In Luke 2, we read about the angels declaring "Glory to God in the highest" (verse 14) and the shepherds "glorifying and praising God for all they had heard and seen" (verse 20) in response to the birth of Christ. Their spontaneous glorifying of God was natural and completely understandable, given the event they were witnessing! But the how-to instructions for glorifying God in this catechism question imply a much longer time frame and a much greater project: learning how to love, trust, and obey God. How do we learn to do that? What does this learning involve? For a couple of good summaries, take a look at what Paul advises in Philippians 1:9-11 and in Ephesians 4:14-24.
If you have kids who've been in Sunday school the past few weeks, you might ask them what they've learned about the Northern Kingdom of Israel. Did the kings and the people they ruled live in a way that glorified God? If not, what were they doing instead? What eventually happened to them?
*When reflecting on this story, don't necessarily rule out Martha as an enjoyer of God! It's interesting to see how Martha reacts to Jesus' presence in verse 38 and then to note what interferes with her pleasure in verse 40.
