Most likely author
– Psalm 73 is headed “A Psalm of Asaph.” The traditional and widely held evangelical view is that Asaph, a leading Levite musician appointed by King David to lead worship, is the author (his name appears as the superscription for Psalm 50 and Psalms 73–83). Asaph and his family are repeatedly associated with temple music in the books of Chronicles (1 Chr. 16; 25), so the Asaph who wrote these psalms is understood as a divinely inspired worship leader in Israel’s cultic life.

Text (KJV)
– Psalm 73:25–26 (KJV): “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.”

Evangelical perspective on authorship and authority
– Evangelicals accept the traditional ascription to Asaph as part of the Bible’s inspired authorship. That means Asaph’s personal reflections are treated not merely as poetry but as Scripture speaking with divine authority for faith and life.
– Even where modern scholars debate precise dating or editorial layers in the Psalter, the evangelical emphasis is that God used Asaph (and the psalmist’s experience) to disclose truth that is timeless and Christ-fulfilling.

Context and themes relevant to vv. 25–26
– Psalm 73 moves from honest spiritual struggle (envy of the prosperous wicked) to holy perspective regained “when I went into the sanctuary of God” (v. 17). Verses 25–26 are part of the psalmist’s climactic confession of total dependence on God.
– Key themes in these verses: God as supreme desire (“Whom have I in heaven but thee?”), God as sufficient portion (“my portion for ever”), and God as sustaining strength in human weakness (“My flesh and my heart faileth: but God is the strength of my heart”).

Christ-centered and practical application (evangelical reading)
– Christ as fulfillment: Evangelicals typically read the psalms Christologically. The deep longing for God and the trust in Him as portion point forward to the ultimate satisfaction and sustaining presence found in Christ (cf. John’s “I am” sayings; New Testament testimonies of Christ as our portion and strength).
– Personal application: These verses encourage believers to fix their desires on God rather than on earthly success, to rely on God when physical strength and emotions fail, and to worship and trust Him as the lasting “portion.”
– Pastoral comfort: Good for times of discouragement, illness, or when the success of the ungodly tempts us to doubt God’s justice—this psalm models honest struggle followed by renewed trust after encountering God.

Useful cross-references
– Lamentations 3:24 — “The Lord is my portion, saith my soul.”
– Philippians 4:13 — “I can do all things through Christ which strengtheneth me” (echoing dependence on God’s strength in weakness).
– Hebrews/NT reading of the Psalms — evangelicals often point to the Psalms as pointing to Christ and as normative for Christian worship and devotion.

Brief devotional suggestion
– Read Psalm 73 slowly, especially vv. 25–26. Confess any attraction to earthly things, bring your weakness to God, and affirm Him as your portion and strength. Pray that the Lord would make these truths more real in daily life.
