How do we know that God uses the weak to accomplish His purposes?

The sermon illustrates that God's choice of Mary, an insignificant young woman from Nazareth, exemplifies His pattern of using those whom the world deems weak or unimportant to accomplish His purposes. 1 Corinthians 1:27 states, 'But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong.' This theme resonates throughout Scripture, showing that God's sovereignty and grace work through human limitations to magnify His glory and power.
