What does Psalm 73:26 mean?

Human beings are fallible. The premise of this psalm is that Asaph wrongly became bitter and unhappy when he could not understand God's ways (Psalm 73:2–3, 21–22). After resolving his unhappiness (Psalm 73:15–18), he declares God as the most important aspect of his life. Even if his health failed, Asaph knew this would not mean God had failed him (Romans 8:38–39). To view God as his "portion," means to see the Lord as the source of his happiness.

Job, too, knew that God would not fail him even if his life should end. He testified, "For I know that my Redeemer lives, and at the last he shall stand upon the earth. And after my skin has been destroyed, yet in my flesh I shall see God" (Job 19:25–26). Abraham also considered God to be his portion. When the king of Sodom offered Abraham a reward for rescuing the people of Sodom when they were captured, Abraham refused the reward. He told the king of Sodom, "I have lifted my hand to the LORD, God Most High, Possessor of heaven and earth, that I would not take a thread or a sandal strap or anything that is yours, lest you should say, 'I have made Abram rich'" (Genesis 14:22–23).
