The head of Ephraim is Samaria, and the head of Samaria is only Remaliah’s son. If you do not stand firm in your faith, you will not stand at all. ( Isaiah 7:9 NIV)
The message here is that neither Israel nor Aram had God as their leader in those days, only Judah had and if God was in charge, what could any foe do? Standing in the faith per se was not assurance for victory, but standing firm in the faith. And so it is now for believers of Jesus Christ in this generation too. We must stand firm in the faith, fixing our eyes on Jesus and following in his footsteps. The Holy Spirit will guide all who make this their aim in life.
