Thomas Brooks emphasizes that God sometimes removes our earthly comforts to draw us into a deeper reliance on Him. He illustrates this through the psalmist's experience of feeling abandoned and turning to God as his only refuge. When all human supports fail, believers are led to fully trust in God, recognizing that true sustenance comes from Him alone. This process of stripping away is ultimately for our spiritual benefit, leading us to declare that all our fountains are found in God.
