These verses contrast God’s eternal salvation and self-existence with the temporary nature of things on earth. If we read Psalm 102:27-28, we find that God has no beginning and no end…He always was and will always be…and finally, He has, within Himself, the power of being, thus He requires no assistance from any outside sources to continue to exist. So hence, any earthly opposition is powerless to do lasting harm to those who believe in Him. For only the Lord alone has power over our final destiny. Jesus stressed this is Matthew 10:28 when He said, “Don’t be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell.” So when the world mocks and despises you for your faith, don’t be discouraged, dismayed, or demoralized…for your eternal Father has your back.
