During the seasons when they honored God, Israel shone brightly (e.g., the fame Solomon enjoyed when the Queen of Sheba visited). But when they became insular and rebellious, Yahweh still used them to reveal his glory to the nations.
There are seasons when we go to the nations willingly. There are seasons when they come to us and we willingly present the beauty of God’s transformative covenant relationship. But there are also times when we are sent against our best-laid plans (e.g., Jonah to Nineveh, Paul under arrest in Rome). And, last but not least, there are the times when God’s people are captives to their enemies in their own land. American Christians have known the first three. I pray we never have to experience the fourth. This only comes as God’s corrective to the persistent rebellion of his people to be a blessing to the people groups [nations].
Yes, I believe the church is being watched in the heavenlies. I believe God is doing something on a grander scale than our faith allows us to see (most of the time). I believe there are times when he pulls back the curtains to give us a kingdom of heaven peek. I believe we are living through intriguing times.
