Self-doubt and insecurities often mask themselves as doubt in God, affecting how we view our relationship with Him. Through biblical examples like Gideon, we learn that God sees us differently than we see ourselves - as mighty heroes and masterpieces created for specific purposes. Our past failures, like those of Moses, David, and Paul, don't disqualify us from God's calling. True confidence comes not from believing in ourselves, but from having faith in God's purpose and His promise to be with us as we fulfill our calling.
