His power is made perfect in weakness
2 Corinthians 12:9

This is opposite to how the world operates. We like to show off our strength. To act like we’ve got it all together. However Gods power is made perfect in weakness. If God’s grace alone is sufficient to sustain me, I can’t take credit for sustaining myself. God does it all, and we will boast only in Him. If you are aware of your weakness, you are also humble and receive grace. The more we acknowledge our nothingness and complete dependence on God, the more He will live and work in us.
