“For with you is the fountain of life; in your light do we see light” (v39). The psalmist declared that God is the source of everything good; we “feast” from His abundance, and we “drink from the river of your delights” (v8). As we spend time with God, we enjoy His goodness and we begin to love what He loves. In contrast, the wicked person dwells on sin “deep in his heart” (v1), and his mind is full of “trouble and deceit” as he makes plans (v2-4).
“How precious is Your steadfast love, O God!” (v7). God’s overflowing love heals us and transforms us into people whose hearts dwell on what is good.
