God created His church (believers) to show His wisdom and greatness, through us, to His creation Ephesians 1:1-12, Ephesians 2:1-7, Ephesians 3:1-12. Evidently, there are created beings in the universe that learn of God's wisdom through God's dealing with humankind.
This teaches us that our lives are far more meaningful that we realize. We are being watched by a great cloud of witnesses Hebrews 12:1, to whom God is showing His wisdom, as they watch the human race. Let this knowledge fill you with wonder, and let it motivate you to be intentional with how you live your life every day!
In fact, Paul prays for us to realize how blessed we are in Christ and how much potential we have to bring glory to God through our faith. You'll see this as you read in Ephesians.
