Isaiah 40 begins with the prophecy of the forerunner and then proceeds to tell of the Servant God will send to deliver His people. It ends with this familiar challenge full of hope:
28 Have you not known? Have you not heard?
The Lord is the everlasting God,
the Creator of the ends of the earth.
He does not faint or grow weary;
his understanding is unsearchable.
29 He gives power to the faint,
and to him who has no might he increases strength.
30 Even youths shall faint and be weary,
and young men shall fall exhausted;
31 but they who wait for the Lord shall renew their strength;
they shall mount up with wings like eagles;
they shall run and not be weary;
they shall walk and not faint.

God begins by asking the question: "Don't you know what God has in store? Haven't you heard the good news?" We're talking God here. He is all-powerful and He shares what He has with His people. He gives strength, courage, and hope to those who are weak, discouraged, and hopeless. God has been around forever and will be around forever. This story is not over. God is not done; neither are you if you trust in Him. Listen and learn to the Good News of Christ's coming. Take heart and trust in Him.
