“God’s kingdom is won not though strength and accomplishment, however, but through the cross. It is entered not by the strong, but by those who admit their weakness and need for grace. This completely changes our attitude toward the poor, the powerless, and the marginal.”
"My grace is sufficient for you, for my power is made perfect in weakness." 2 Corinthians 12:9
