There is nothing on earth I desire beside you.
My flesh and my heart may fail, but God is the strength of my heart and my portion forever. PSALM 73:25-26
When you can say with the psalmist that there is nothing on earth I desire beside you, then whatever happens, good or bad, will not affect you much, since in the first place you don’t bother much about it.
Desire only God. And the things of this world will fade away, in the light of His glory & grace.
Psalm 27:4 (KJV) One thing have I desired of the Lord, that will I seek after; that I may dwell in the house of the Lord all the days of my life, to behold the beauty of the Lord, and to enquire (study)in his temple.
