"And now you think to withstand the kingdom of the LORD, which is in the hand of the sons of David . . . "
Judah's king Abijah is here warning Israel's idolatrous king Jeroboam, that it is futile to fight against the Lord and His church. Jeroboam (the bad guy) had twice the number of soldiers as Abijah (the good guy) had; and yet God gave Abijah a great and resounding victory, (see v. 15 ff.).
The church may be way outnumbered by the world (no doubt)--but the church has Jesus, the Great "Son of David" on her side. Therefore, we should take encouragement, and fight the battles of our Lord--knowing that He is our victorious Captain.
