What does it mean that God waters His garden?

The image of God watering His garden symbolizes His active role in the spiritual nourishment of His people. Just as rain nourishes the earth, the Word of God is described as life-giving, nourishing His creation. In Psalm 104, we see that the waters from the mountains provide drink to every beast of the field, paralleling how God's Gospel sustains His people spiritually. This illustrates the truth of Isaiah 35:7, where the parched ground shall become a pool, showing how God transforms our spiritual dryness through His Word, leading to regeneration and growth in faith.
