A.B. Simpson emphasizes the vast potential of the human soul, created in God's image, and the transformative power of the Holy Spirit in realizing this potential. He encourages believers to allow God to cleanse and fill their hearts, enabling them to become the temple of His presence. Simpson highlights that through the Holy Spirit, dormant abilities are awakened, leading to a fuller understanding of God's purpose for our lives. Ultimately, he invites us to marvel at the divine craftsmanship in our lives and to recognize our worth in God's eyes.

If we would be enlarged to the full measure of God's purpose, let us endeavor to realize something of our own capacities for His filling. We little know the size of a human soul and spirit. Never, until He renews, cleanses and enters the heart, can we have any adequate conception of the possibilities of the being whom God made in His very image, and whom He now renews after the pattern of the Lord Jesus Himself. We know, however, that God has made the human soul to be His temple and abode. God knows how to make the house that can hold His infinite fullness. We know something of this as all our nature quickens into springtime life at the coming of the Holy Spirit. We know it as from time to time new baptisms awaken the dormant powers and susceptibilities that we did not realize we possessed. Let us give God the right to make the best of us. Filled with wonder, we shall some day behold the glorious temple that He has built and say, Lord, what is man, that thou art mindful of him? (Psalm 8:4).
