“Lord, Thou hast been our dwelling place in all generations. Before the mountains were brought forth, or ever Thou hadst formed the earth and the world, even from everlasting to everlasting, Thou art God.” Psalm 90:1-2 (KJV)
This Psalm is called “A prayer of Moses the man of God”. Though I cannot prove it; I personally believe that Psalms 90 -100 are Psalms of Moses, because of the way they are written and references to the wilderness, and to God; that only a man who lived there would know.
The best place for any generation, for any individual to dwell is in the Lord. He has made that possible through the death, burial and resurrection of His Son Jesus Christ. How was Moses, the children of Israel able to dwell in God? Today we are saved, and dwell in God because we look back to the cross, and believe. The children of Israel, Moses, and all the believers of the Old Testament looked ahead to the cross of Christ and believed., and dwell in God
Moses, and all who believe in Him, dwelling in Him, knows that He is everlasting; that He is God, and we dwell in Him. He is the Sovereign; the Almighty. In Him we can trust. In Him we dwell.
