One of my favorite quotes is from Plato – "Be kind, for everyone you meet is fighting a hard battle." Jesus promised us as much. (John 16:33) In Psalm 76:2-3 there is an important principle for fighting those battles.
"In Salem [Jerusalem] also is His tabernacle
And His dwelling place in Zion.
There He broke the arrows of the bow,
The shield and sword of battle." (NKJV)
Did you see it?
It was in the tabernacle, the temple, His dwelling place in Zion, that the victory was actually won. The prayer, the worship, the offerings and consecration the soldiers underwent before they ever took the battlefield was what sealed their ultimate triumph.
The battle is won in worship.
