The psalmist was envious of the wicked, upset that though he tried to live a righteous life, he was not prospering as the wicked man was. He was having difficulty understanding the prosperity of the wicked until he went into the sanctuary... Psalm 73:16 But when I thought how to understand this, it seemed to me a wearisome task, 17 until I went into the sanctuary of God ; then I discerned their end. We need quiet time with God for many reasons, but this is one of them - to discern truth about life. Spending time with God helps me remember why I'm here and what this life is all about. In case we forget - the Psalmist reminds us at the end of this song... 25 Whom have I in heaven but you? And there is nothing on earth that I desire besides you. 26 My flesh and my heart may fail, but God is the strength of my heart and my portion forever . Lord, our flesh will fail. Be our strength and our portion.
