Great Power in a Jar of Clay

Scripture
2 Corinthians 4:7-8 We now have this light shining in our hearts, but we ourselves are like fragile clay jars containing this great treasure. This makes it clear that our great power is from God, not from ourselves.

Observation
A shining light of the gospel in our lives, but clearly not originating from humanity. Great Power, not impotence. GREAT POWER in a clay jar; an earthen vessel.

Application
I need to make sure the light is actually shining in my heart. I need to be 'in front' of the source of light, allowing Jesus to shine in me. I need my life postured before His Word, His Throne, His Grace. And then Paul writes about Great Power. Where is this great power in my life? I feel like the greatness of the power should be so great that it is obviously not from me. Paul writes "This makes it clear...". Unfortunately, it doesn't appear I live in any great power, or at least power beyond what is normal for a modern day christian. I look at different men throughout history who demonstrated great power, and it was clear it was the power of God.

Prayer
Lord, I thank You for shining the light of the glorious gospel into my heart. I thank You for saving me, and bringing transformation to my life. Truly, I am a fragile jar of clay. I need Your transforming power and the brightness of Your glory to shine through my life, that people may see Your Great Power - and the power of Your love.
