From the beginning of scripture we see that God is eternal and constant. He was before creation and will be for eternity (Genesis 1:1).
Not only His presence is eternal, but also His love for His people and His righteousness. His righteousness does not change. Righteousness is not a word that defines God, rather God is the person who defines righteousness. He has chosen to reveal His righteousness to His people through His Word (Deuteronomy 4:8).
"Oh constant God throughout the ages
This word, revealed as The Law of God in the Old Testament, and revealed further in Christ, which is now written on our hearts, will never falter. Furthermore, by the Spirit of God, it is living and active in the life of a believer (Hebrews 4:12). In His Word we can trust.
"Your Word it speaks and never falters
In the chorus of this song the immutability of God comes together as a reminder and picture of the gospel. He is unchanging, worthy of all glory, and reigning supreme on His throne. All the while we are unworthy, wretched sinners who have no right to stand before the King of Kings. BUT in Christ, the Word, the Lord has chosen to redeem us. By the blood the Son of God shed, the Father now looks not upon our unrighteousness, but upon the righteousness of Christ which unlike us, does not falter or change. In the righteousness of Christ we are secured.
James 1:17-18 says:
"Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shadow due to change. Of his own will he brought us forth by the word of truth, that we should be a kind of first fruits of his creatures."
This gift of righteousness is from the unchanging Father, who brought us forth by the word of truth, His own righteousness, that we might be called sons and daughters of the King, first fruits of His creation, and lovely in His sight.
"Unchanging God, all glory to Thee
Lastly, verse three reminds us that the Lord’s strength is perfect in our weakness. We can rely upon Him, even when we might not understand (2 Corinthians 12:9). Though in our fallen state we cannot fully comprehend certain aspects of God's nature, we continue to trust, knowing that His strength is perfect, His character and righteousness are unchanging, and His word will not falter.
"Though I am weak you are perfection
