A.B. Simpson emphasizes the essence of faith through the story of an elderly woman who succinctly defines it as believing that God has already accomplished what we ask of Him. He warns against the tendency to doubt and interfere after praying, suggesting that true faith means to commit our ways to the Lord and trust in His ability to fulfill His promises. Simpson encourages believers to relinquish control and allow God to complete His work in their lives, affirming that faith is about resting in God's assurance and letting go of our struggles.

Rarely have I heard a better definition of faith than one given by a dear old woman, as she answered the question of a young man on how to take the Lord for needed help. In her characteristic way, pointing her finger toward him, she said with great emphasis, "You've just got to believe that He's done it, and it's done." The great danger with most of us is that after we ask God to do something, we do not believe it is done. Instead we keep on helping Him and getting others to help Him-superintending God. Faith adds its amen to God's yea, and then takes its hands Off, and lets God finish His work. Its language is, Commit thy way unto the Lord; trust also in Him. And God worketh. Lord, I give up the struggle, To Thee commit my way, I trust Thy Word forever, And settle it all today.
