What does it mean that God is all-sufficient?

Q162 · Faith in God and Our Knowledge of Him

God is all-sufficient within Himself. He has no need to be served, worshipped, or glorified by others. Rather, it is we who need to serve Him, worship Him and glorify Him, entering into a relationship with Him through His grace working within us, overflowing with holy life, inner joy, and fulfilment; “for in Him we live and move and have our being” (Acts 17:28).
