The things of this world fail. Businesses fail. So do cars, appliances, and the like. Some marriages fail. Even our own bodies fail. But there is something that doesn't fail, something that we can count on. That something is God's love and faithfulness (Psalm 100:5). God's love endures forever! We have been promised by God that He will never leave us and He will never forsake us (Hebrews 13:5).
We need to set our hearts and our minds on things that last. We should not set them on the things of this world, such as money, success, and possessions. There is no guarantee that those things will last. We need to set our hearts and minds on God. Our desire should be for Him. He is eternal and His love endures forever. Psalm 73:26 says that, although our flesh and our hearts may fail, He will always be the strength of our hearts and our portion forever. In each day of our lives, both now and through eternity, He is all that we need.
