Claiming to follow the Lord or saying that we seek Him means nothing if our actions violate His Word. It is easy to apply this verse to our government -- we say "in God we trust" or "God bless America" yet as a whole, our actions deny God as King. But what about at personal level? We can say we're leaning on God, trusting in Him, seeking Him, yet are our actions rooted in personal glory, selfish decisions, and carnal gain?
Some of my favorite verses. Work however God has gifted us, our focus on the glory of God.
We often quote verse 7 alone, but it is connected to verse 6 -- it takes humility to fully cast our cares on Christ.
