The second verse of the hymn “Great Is Thy Faithfulness” speaks of the dependable patterns of nature. “Summer and winter, and springtime and harvest, / Sun, moon, and stars in their courses above, / Join with all nature in manifold witness / To Thy great faithfulness, mercy, and love.” The hymn writer notes the rhythm of God’s creation. Each season, each day, follows a regular pattern. When we wake up in the morning, we can be certain that the sun will rise.
By looking at this example from nature, we know that we can depend on the Creator. In this psalm, God addresses His servant David. David was chosen by God to be the king of Israel. This unknown young man was handpicked instead of many more likely candidates to lead God’s people. What an honor it must have been to be chosen by God for such a mission.
We would like to think that David, realizing the depth of God’s faith in him, would be perfectly honest, faithful, and obedient. That wasn’t the case. David broke his promises. He sinned against God, his people, and his neighbor. But despite these failures, God did not go back on His covenant with David and with the nation of Israel.
This psalm describes the relationship between David and God. God promises to love David “forever” and desires, in return, David’s faithfulness. This may seem a daunting task, knowing our tendency to fail. But the remarkable thing about God is that even when we disobey and God disciplines us, our acts will not reduce God’s faithfulness. A promise from God can be counted on completely.
The psalm compares the everlasting faithfulness of God to nature. Just like the moon and sun appear each day in the sky, God will forever be faithful to His covenant promises.
