In Isaiah 41, God speaks through Isaiah assuring His children, His faithful remnant, that He will help them through the exile. He will rescue His children. He challenges the false idols that His children choose to chase after as they double down on idol production in preparation for what's coming rather than looking to God for strength and protection. The world can only provide what it knows and if it doesn't know God, it's completely useless. God knows the future and loves us beyond comprehension. Idols in our lives do not. Idols are worthless while God is victorious. We can trust God with everything we've got and lean on Him through every turbulent valley. He is the First and the Last and He is God.
