There is a war happening all around us that we can't see. Principalities and powers are moving and working in the spiritual realm. Pastor David is reminding us of the battle raging back and forth between Satan and the Lord. They're battling for our souls! We need to come to realize that the things happening that we can't see are more powerful than we comprehend. The fight is continuous and won't end until Satan is thrown into the lake of fire. Until then, we'd be wise to be armed with the Word of God!
