1 Chronicles 5:22

Warrior, fighting under the banner of the Lord Jesus, observe this verse with holy joy, for as it was in the days of old, so it is now: if the war is of God, the victory is sure. The sons of Reuben, the Gadites, and the half-tribe of Manasseh could barely muster forty-five thousand fighting men; yet in their war with the Hagarites, they slew men, an hundred thousand, for they cried to God in the battle, and He was entreated by them, because they put their trust in Him. The Lord does not save by many or by few; it is for us to go forth in Jehovah’s name, even if we are only a handful of men, for the Lord of Hosts is with us as our Captain.

They did not neglect buckler, sword, and bow, nor did they place their trust in these weapons. We must use all fitting means, but our confidence must rest in the Lord alone, for He is the sword and the shield of His people. The great reason for their extraordinary success lay in the fact that the war was of God. Beloved, in fighting with sin without and within, with doctrinal or practical error, with spiritual wickedness in high or low places, with devils and the devil’s allies, you are waging Jehovah’s war. Unless He Himself can be defeated, you need not fear defeat.

Do not quail before superior numbers, do not shrink from difficulties or impossibilities, and do not flinch at wounds or death. Smite with the two-edged sword of the Spirit, and the slain shall lie in heaps. The battle is the LORD’s, and He will deliver His enemies into our hands. With steadfast foot, strong hand, dauntless heart, and flaming zeal, rush to the conflict, and the hosts of evil shall fly like chaff before the gale.

Stand up! stand up for Jesus!
The strife will not be long;
This day the noise of battle,
The next the victor’s song.
To him who overcomes,
A crown of life shall be;
He with the King of glory
Shall reign eternally.
