How do we know that God uses people to carry out His purposes?

God's sovereignty is affirmed in His choice to work through human agents to fulfill His will. In Judges 4, we observe Deborah, a prophetess and judge, being chosen by God to lead His people Israel out of oppression. Despite the formidable enemy represented by Jabin and his military might, God equips Deborah and Barak to achieve victory. This demonstrates that God uses those who trust Him, showcasing His ability to work through all kinds of people, regardless of their social standing or perceived capabilities. By this means, He not only achieves His purposes but also magnifies His glory through their acts of faith and courage.
