How much worse can the news get? The story of the Exodus shows God working out his purposes on a long timescale. The coming of Moses was part of God's purpose.
God's promise to Abraham
1. Countless offspring.
2. Four hundred years as strangers.
3. Return to the promised land.

Our struggle is not against flesh and blood.

God doesn't change. He is still at work. However evil the world grows we should look in faith to God whose promises are sure to be fulfilled.
