This coming Sunday is the 5th Sunday after the Epiphany, according to the Three year series. Here is the Old Testament reading.
These are just preliminary thoughts about how to approach the text. Isaiah speaks to a people who have become downcast, discouraged, and from their perspective all seems lost, no evidence that God is in control. Thus, we find the refrain: “Don’t you know? Haven’t you heard?” (v. 21 and v. 28).
In both cases, Isaiah begins the answer with “God is…” and “The eternal God…” specifying first God’s strength/power and then His character. Then God provides the ultimate comfort in vv. 29-31
29 He gives strength to those who grow tired
and increases the strength of those who are weak.
30 Even young people grow tired and become weary,
and young men will stumble and fall.
31 Yet, the strength of those who wait with hope in the LORD will be renewed.
They will soar on wings like eagles.
They will run and won’t become weary.
They will walk and won’t grow tired.
When Jesus Christ fulfills all things, it includes these promises of God. If you are tired, then God strengthens you, sometimes in surprising ways, sometimes unseen. This who wait with hope in the Lord—they will be renewed. May this comfort, encourage, and strengthen as we live in this time.
