God "dwells in light" (1 Timothy 6:16; 1 John 1:7), in heaven (Psalm 123:1), in his church (Psalm 9:11; 1 John 4:12). Christ dwelt on earth in the days of his humiliation (John 1:14). He now dwells in the hearts of his people (Ephesians 3:17-19). The Holy Spirit dwells in believers (1 Corinthians 3:16; 2 Timothy 1:14). We are exhorted to "let the word of God dwell in us richly" (Colossians 3:16; Psalm 119:11).
Dwell deep occurs only in Jeremiah 49:8, and refers to the custom of seeking refuge from impending danger, in retiring to the recesses of rocks and caverns, or to remote places in the desert.
