How do we know that God is everywhere?

Psalm 139 illuminates the truth of God's omnipresence, which means that God is not limited by time or space. David asks rhetorically, 'Whither shall I go from thy spirit? or whither shall I flee from thy presence?' (Psalm 139:7). He concludes that there is no place one can escape from God's presence, illustrating that whether in heaven or hell or anywhere in between, God is there. This means that for believers, God's constant presence provides assurance and security, as He is always guiding and holding us. In every circumstance, God is intimately aware of our situation, and we can have confidence that we are never alone.
