Do you not know? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. (Isaiah 40:28 NIV)
Our everlasting God is the same yesterday, today, and forever.
We can rest in God because He and His character and purposes are everlasting. He is never-changing. His faithfulness and truth endure forever. He is the Alpha and the Omega.
Because God’s character is permanent, His salvation plan is the same as yesterday, today, and tomorrow. All the promises of God have been fulfilled. And because God is I AM, the everlasting God, He will keep the rest of His promises. That leaves us hope-filled and joyous. How can we be this blessed? Because God’s mercy and loving-kindness are everlasting.
“Nothing can alter the character of God. In the course of a human life, tastes, outlook and temper may change radically: a kind, equitable man may turn bitter and crotchety: a man of good-will may grow cynical and callous. But nothing of this sort happens to the Creator. He never becomes less truthful, or merciful, or just, or good, than He used to be.” - J. J. Packer
