Remember that, as you read through your bibles. Look for this plan of salvation for humanity in Jesus Christ, look for it on every page. The Catechism points out that we have the first dim strains of God's Master Plan already in the Garden of Eden when He promises a future of hope to two cowering humans, Adam and Eve. That's recorded in Genesis 3.15. They trudged through life always looking for the One to come who was going to do what God promised, to crush the head of the serpent who had brought so much misery into God's perfect creation.
Time moves on, but the plan never falters.
The nation of Israel is assembled. The centuries roll by, and prophets come. He hasn't forgotten. He hasn't changed His mind. Though things may sometimes seem dark and hopeless, they are not out of control.
