How do we know God uses small things?

In 1 Corinthians 1:27-29, Paul explains that God has chosen the foolish and weak things of the world to shame the wise and strong. This principle is evident throughout Scripture - from David, a humble shepherd, defeating Goliath, to the feeding of 5,000 with five loaves and two fish. God delights in using small things, highlighting His sovereignty and ensuring that no one can boast in His presence. This encourages believers to embrace their smallness, knowing that God's power is made perfect in weakness.
