Psalms 73:26

²⁴ Thou shalt guide me with thy counsel, and afterward receive me to glory.

²⁵ Whom have I in heaven but thee? and there is none upon earth that I desire beside thee.

My flesh and my heart faileth: but God is the strength of my heart, and my portion for ever.

²⁷ For, lo, they that are far from thee shall perish: thou hast destroyed all them that go a whoring from thee.

²⁸ But it is good for me to draw near to God: I have put my trust in the Lord GOD, that I may declare all thy works.

Do read the surrounding verses too, because the context often says more than a single verse.
