These words spoke truth to me this week. These comments are made in reference to Hebrews 13:8: “Jesus Christ is the same yesterday, today, and forever.”:
“Christ is always the same. Here at the end of his letter, the author echoes a theme from its beginning. ‘To the Son He says:…You [remain] the same’ (Hebrews 1:8, 12 citing Psalm 102:27). But now he makes explicit what earlier was implicit. The immutable One of Psalm 102 is none other than the incarnate One of the gospel.
The practical implication of this becomes clear when we remember that Psalm 102 is possibly the most eloquent description of depression and despair to be found in the entire Psalter. The psalmist’s mental salvation lay in his rediscovery of the immutability of God. Hebrews gives that truth flesh-and-blood dimensions in Jesus Christ. You can trust Him, He is always the same.
Do not mistake the meaning. This is not the immutability of the sphinx – a Christ captured once and for all in a never fading still photography. This is the changelessness of Jesus Christ in all His life, love, holiness, grace, justice, truth, and power. He is always the same for you, no matter how your circumstances change.
Say this to yourself when you rise each day, when you struggle, or when you lay on your pillow at night: ‘Lord Jesus, you are still the same, and always will be.’”
