He has made everything beautiful in its time. Also He has put eternity in their hearts, except that no one can find out the work that God does from beginning to end.
Ecclesiastes 3:11

Our journey through life is like children who anticipate Christmas morning. They know something exciting awaits them, but they don’t know what it is until they unwrap it. Likewise, God has put in the human heart a longing, anticipation, and expectation that eternal joy is coming, yet for now we can’t know the totality of God’s plans and purposes until they are revealed. So we live in a state of expectation and trust in the present: expectation based on God’s promises and trust based on His faithfulness.

The nation of Israel lived with that same tension. After Moses led them in renewing their covenant with God before entering the Promised Land (Deuteronomy 29), he warned them about the consequences of being unfaithful and how those consequences would unfold. Some things are revealed, but the “secret things” belong to the Lord alone until they are revealed (verse 29).

Rejoice today in the eternal longing God has put in your heart and renew your faith in Him for the “secret things”—His plans and purposes—yet to be revealed.

God takes us into His confidence and shares His secrets with us.
J. I. Packer
