What do you do when you are living in God's ellipsis of silence?

Jeremiah 29:11 tells us that God has plans for us that will not harm us. The context of this scripture is that the people of Israel were in a state of great vulnerability. They were in Babylonian captivity, yet the Lord tells them to build houses, plant gardens, and give their sons and daughters in marriage. This does not sound like a short-lived exile; their captivity was going to continue for 70 years in exile, waiting on their deliverance. The Israelites need to focus on the season that they're in so that they can thrive and prepare for the next season.
