"Jesus Christ is the same
yesterday, today, and forever."
Who else can this be said of? As for man, we know that "all have sinned and come short of the glory of God." (Romans 3:23) But not Him. "One who has been tempted in all things as we are, yet without sin. " (Hebrews 4:15) Sin changes everything. But not our Lord.
This means from the Beginning. When God said, "Let Us make man in Our image" to Proverbs 8, "To Then I was beside Him, as a master workman; And I was daily His delight, Rejoicing (playing) always before Him, Rejoicing (playing) in the world, His earth, And having my delight in the sons of men." Jesus is the same one who made us while playing around and still delights in us.
He has not changed from the Beginning up to now. It means He more than kinda-sorta likes us, loves us, which is incomprehensible He delights in us. I think He is itching to get His hands back on us to keep playing, molding us into who He wants us to be: the One who changes not, changing us to conform to His image.
Even when we get old and forget yesterday and barely can remember things today, we can still be assured of our forever, because of Him. Men die, but He ever lives to make intercession for us. He is "the lamb slain from the foundation of the world." (Revelation 13:8) That means way back then, as He was rejoicing in the creating of the earth, delighting in the sons of men, there was the shadow of the cross because of our sin. Only in heaven will it be finally gone when we join the throngs of the redeemed singing, "Holy, Holy, Holy!" "And He who sits on the throne said, 'Behold, I am making all things new.'" (Rev. 21:5)
"Jesus Christ the same yesterday--In all past times there was no way to the holiest but through the blood of Jesus. Today--He is the lamb newly slain, and continues to appear in the presence f God for us. Forever--to the conclusion of time, He will be the way, the truth, and the life, none coming to the Father but through Him; and throughout eternity." (Adam Clarke)
Didn't I mention recently that one of my favorite verses is James 1:17. "Every good thing given and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shifting shadow." When we get to heaven, this Father of lights will be our only light.
"And the city has no need of the sun or of the moon to shine on it, for the glory of God has illumined it, and its lamp is the Lamb...(for there will be no night there). (Rev. 21:23, 25)
We have no idea of the bondage of those who worship idols whose supposed whims, changeableness keep people in the bondage of fear trying to placate them. But we have in this verse the assurance that He is unchangeable. He says it, He means it, and we can stake our lives on it, because He staked His life for us on the cross.
