The Lord, he it is that doth go before thee; he will be with thee, he will not fail thee, neither forsake thee: fear not, neither be dismayed. (Deuteronomy 31:8)
In the presence of a great work or a great warfare, here is a text which should help us to buckle on our harness. If Jehovah Himself goes before us, it must be safe to follow. Who can obstruct our progress if the Lord Himself is in the van? Come, brother soldiers, let us make a prompt advance! Why do we hesitate to pass on to victory?
Nor is the Lord before us only; He is with us. Above, beneath, around, within is the omnipotent, omnipresent One. In all time, even to eternity, He will be with us even as He has been. How this should nerve our arm! Dash at it boldly, ye soldiers of the cross, for the Lord of hosts is with us!
Being before us and with us, He will never withdraw His help. He cannot fail in Himself, and He will not fail toward us. He will continue to help us according to our need, even to the end. As He cannot fail us, so He will not forsake us. He will always be both able and willing to grant us strength and succor till fighting days are gone.
Let us not fear nor be dismayed; for the Lord of hosts will go down to the battle with us, will bear the brunt of the fight, and give us the victory.
