Psalm 62:1 states, “Truly my soul finds rest in God; my salvation comes from him” (NIV). This verse expresses a deep trust and reliance on God, which is a common theme in the Psalms.

The authorship of the Psalms is traditionally attributed to several figures, with King David being the most prominent. From an evangelical Christian perspective, David is often considered the author of many Psalms, including Psalm 62.

### King David:

1. **Background**: David was the second king of Israel and is known for uniting the tribes of Israel, establishing Jerusalem as the capital, and making significant contributions to the worship practices of Israel, including the establishment of the Temple (although he did not build it himself).

2. **Spiritual Significance**: David is frequently portrayed in the Bible as a man after God’s own heart (1 Samuel 13:14; Acts 13:22). His life experiences, from being a shepherd to facing great trials as a king, informed his writings, allowing him to articulate profound expressions of faith, despair, hope, and praise.

3. **Thematic Elements**: In many of the Psalms attributed to David, including Psalm 62, themes of trust in God, finding refuge in Him, and a longing for spiritual rest are prevalent. David’s life was characterized by many challenges—military battles, personal betrayals, and family struggles—which make his reliance on God particularly relatable to believers.

4. **Evangelical Perspective**: Evangelicals view the Psalms not only as historical and poetic literature but also as divinely inspired scripture that has applications for contemporary faith and life. Psalm 62, in particular, is often cited in discussions about faith during trials and the importance of finding solace and salvation in God alone.

In summary, from an evangelical Christian perspective, King David is the most likely author of Psalm 62:1, reflecting his deep relationship with God and emphasizing the importance of finding rest and salvation in Him amid life’s challenges.
