You who bring good news . . . lift up your voice with a shout, lift it up, do not be afraid; [saying] . . . “Here is your God!”

— Isaiah 40:9

The good news that must be announced with a shout is that the Lord has come to make himself known. Knowing and glorifying God is the reason for life itself. The prophet announces: “Here is your God!”Who is this God? This is the Lord who made covenant promises long ago with his people. This is the God who keeps promises, despite the failures and sins of his people for many generations. Though the people had to be disciplined, they remained the people of God. Similarly, the Lord does not give up on us, despite our unfaithfulness.This is the God of all grace. He is rich in forgiveness and abounding in mercy. He is the faithful God who keeps his word, for he has proclaimed restoration. He loves, and he disciplines. He disciplines, and he forgives. He forgives, and he restores. The prophet presents God to the people so that they may know him.The people who know God are strong and active. Our greatest need is to know God. He is eternal, unchanging, all-knowing, all-powerful, transcendent, and sovereign. He is holy and just, faithful and true, kind and merciful. God is our creator, provider, protector, redeemer, comforter, and reward. He is our joy, peace, righteousness, refuge, and strength. In him we have eternal security, full life, and a sure salvation.

Lord, help us to know you. Be our strength and joy. Reveal your holiness, mercy, and power, and anchor our lives in your unchanging love and salvation. In Jesus, Amen.
