F.B. Meyer emphasizes that God's work often occurs without visible signs, as illustrated in 2 Kings 3:17, where the valley is filled without wind or rain. He points out that in both church work and personal Christian experience, we may not see immediate evidence of God's blessings, yet He is actively at work beneath the surface. Meyer encourages believers to trust that even when they do not perceive God's presence or action, He is fulfilling their desires and filling their spiritual needs. The sermon reassures that true success in God's work is not measured by outward manifestations but by the quiet, transformative work happening within.
