2 Chronicles 13:18 Thus the children of Israel were brought under at that time, and the children of Judah prevailed, because they relied upon the Lord God of their fathers.
In the Civil War between Judah and Israel, Ahijah and his people prevailed and slaughtered the army of Israel, the breakaway Northern kingdom under Jeroboam. Judah prevailed because they relied upon the Lord. Judah may not have been so great, but they did rely on the Lord. God was faithful to their faithfulness and granted them victory over their enemies. They did not rely on their strength or numbers, but on the promises of God. For out of Judah will come the Savior, our Messianic Deliverer.
We are small and weak in the face of our spiritual enemies, but God is our fortress and champion because of Christ. We can count on Him to prevail over our enemies, and we win the victory. Satan is bound, Sin is overcome, and Death is no more. These deadly enemies of our soul have been utterly slaughtered at the cross and the empty tomb. Count on it! Trust the Lord to grant the victories He promised, even through all the little troubles and battles we face.
