Scripture Reading: Lamentations 3:19–26
Key Verses: Lamentations 3:22–23
Through the Lord’s mercies we are not consumed, because His compassions fail not. They are new every morning; great is Your faithfulness.
The first verse of the hymn “Great Is Thy Faithfulness,” by Thomas Chisholm, speaks to God’s faithfulness:
Great is Thy faithfulness, O God my Father!
There is no shadow of turning with Thee;
Thou changest not, Thy compassions, they fail not:
As Thou hast been Thou forever wilt be.
These famous words summarize a foundational truth: God is faithful, and He does not change (Hebrews 13:8). Theologians call this God’s “immutability.” Have you ever thought about why it is so important to understand this aspect of God’s character? God’s unchanging nature is the basis for everything we believe about Him.
If God could change on a whim, then every promise He made in Scripture would be invalidated. He would be untrustworthy. He loved you unconditionally yesterday, but what about tomorrow when you really blow it? That is why God emphasizes His absolute, uncompromising faithfulness throughout His Word. We need that assurance in order to know Him as God and to place our faith in Him.
In 1 Corinthians 1:9 we read, “God is faithful, by whom you were called into the fellowship of His Son, Jesus Christ our Lord.” Your salvation is guaranteed, because He sealed your redemption at the Cross. Let your heart rejoice and say, “Great is Thy faithfulness!”
Father, Son, Holy Spirit—triune God—You have ever been the same, unchanging. Thank You for Your faithfulness. I offer You my heart to mirror that faithfulness.
