Psalms 90—92 concern the saints’ deeper experience of God in their being identified with Christ. Psa. 36:8 speaks of drinking the river of God’s pleasures and eating the fatness of God’s house, indicating that we can experience the Lord by eating and drinking Him (cf. John 6:48-58, 63; 7:37; 1 Cor. 10:3-4; 12:13). According to Moses, the giver of the law and the writer of this psalm, we can also dwell in the eternal Triune God as our Lord (v. 1; 91:9; Deut. 33:27; cf. John 15:4; 1 John 4:15-16; Rev. 21:22). To dwell in God is to have our living in God (Col. 2:6; 3:3; 1 John 4:16), taking Him as our everything. This is deeper than eating and drinking Him. To take God as our habitation, our eternal dwelling place, is the highest and fullest experience of God.
Book Four of the Psalms unveils the saints’ deeper experience of God in the identification with Christ, and God’s recovery of His title and right over the earth. This indicates that our experience of dwelling in God paves the way for Christ to come to possess the earth that God may recover His title (ownership) and right over the earth (see note Psa. 93:11a). Without the saints’ deeper experience of God, God has no way to recover this title and right.
