REFLECTIONS FOR A NEW HEART: Paul’s Prayer for True Spiritual Knowledge (Ephesians 1:15-19a)

That You May Know the Hope, Riches, and Power You Possess

Main Idea of Ephesians:

Ephesians reveals God’s eternal plan to unite all things in Christ, detailing our spiritual riches, the Church’s unity as His body, and our calling to live out this new identity.

Questions to Consider:

Upon hearing of the Ephesians’ “faith” and “love” (v. 15), what are Paul’s two immediate and constant responses (v. 16)?

What specific gift does Paul ask the “glorious Father” to give the believers (v. 17)? What is the ultimate goal of receiving this “spirit of wisdom and revelation”?

Paul prays for the “eyes of your heart” to be enlightened. What is the purpose of this spiritual illumination?

What are the three specific and profound realities that Paul wants the believers to know as a result of this enlightenment (vv. 18-19a)?

The Text:

“This is why, since I heard about your faith in the Lord Jesus and your love for all the saints, I never stop giving thanks for you as I remember you in my prayers. I pray that the God of our Lord Jesus Christ, the glorious Father, would give you the Spirit of wisdom and revelation in the knowledge of him. I pray that the eyes of your heart may be enlightened so that you may know what is the hope of his calling, what is the wealth of his glorious inheritance in the saints, and what is the immeasurable greatness of his power toward us who believe..”

– Ephesians 1:15-19a (CSB)

Observations:

Verse 15: Paul’s motivation for his prayer is hearing of the Ephesians’ “faith in the Lord Jesus” and their “love for all the saints.”

Verse 16: He responds with ceaseless “giving thanks” and “remembering you in my prayers.”

Verse 17: His specific petition is that God would give them “the Spirit of wisdom and revelation.” The purpose of this gift is to attain a deeper “knowledge of him.”

Verse 18: He prays for the “eyes of your heart” to be “enlightened.” The goal is so they “may know” three things.

Verses 18-19a: The three things they are to know are: (1) “the hope of his calling,” (2) “the wealth of his glorious inheritance in the saints,” and (3) “the immeasurable greatness of his power toward us who believe.”

Interpretation:

Thanksgiving Rooted in Faith and Love (vv. 15-16): Paul transitions from his doxology of praise to God into his intercessory prayer for God’s people. The catalyst for his prayer is the good report he has received of their “faith in the Lord Jesus and your love for all the saints.” As John Stott (BST) would point out, these two marks—faith (our vertical relationship with God) and love (our horizontal relationship with fellow believers)—are the essential and inseparable evidences of genuine Christian life. Upon hearing this, Paul’s heart overflows in constant thanksgiving and earnest prayer, demonstrating that the spiritual health of the church is a pastor’s greatest joy and chief concern.

The Petition: To Know God More Deeply (v. 17): The core of Paul’s prayer is not for the Ephesians’ material well-being or a change in their circumstances, but for their spiritual enlightenment and deeper intimacy with God. He asks the “glorious Father” to grant them “the Spirit of wisdom and revelation in the knowledge of him.” This is not a request for new, extra-biblical information, but for the Holy Spirit to illuminate their minds and hearts to truly and experientially grasp the significance of the revelation already given in the gospel. As Peter T. O’Brien (PNTC) might argue, the ultimate goal of all spiritual wisdom and revelation is not abstract knowledge, but a deeper, more personal, and transformative “knowledge of him” (God).

The Result: Enlightened Hearts That Comprehend (vv. 18-19a): Paul further specifies the outcome of this Spirit-given wisdom: “that the eyes of your heart may be enlightened.” He prays for their inner being, the seat of their understanding and affection, to be flooded with divine light. This enlightenment has a specific purpose: “so that you may know” what you already possess in Christ. He wants them to move from a theoretical understanding to a deep, personal comprehension of three glorious realities:

  1. The hope of his calling: The certain, secure, and confident expectation that is attached to God’s effective summons into salvation. This hope is not wishful thinking, but a future certainty of eternal life and glory.
  2. The wealth of his glorious inheritance in the saints: As Frank Thielman (BECNT) might note, this is a stunning phrase. It most likely refers not to the inheritance believers will receive, but to the believers themselves as God’s treasured inheritance, His special possession, highlighting how much God values His people.
  3. The immeasurable greatness of his power toward us who believe: Paul wants them to grasp the sheer, boundless, and incomprehensible magnitude of the divine power that is continually at work for and in those who have faith.

Application:

Pray for Spiritual Wisdom: Regularly pray not just for things, but for spiritual wisdom and revelation for yourself and other believers, asking God to help you truly know Him more deeply.

Know Your Hope: In times of uncertainty or discouragement, anchor yourself in the certain “hope of his calling”—the glorious and secure future God has promised His children.

Understand Your Value to God: Reflect on the incredible truth that the church, His people, is considered the “wealth of his glorious inheritance.” You are His treasured possession.

Trust in His Power: Recognize that the mighty power of God is not just a historical fact but a present reality available for you in your daily walk, struggles, and service.

Connection to the Main Idea:

This passage powerfully connects to the main idea of Ephesians by functioning as a prayer for believers to fully comprehend the very “spiritual riches” the letter details. Paul’s prayer for them to know their hope, their value as God’s inheritance, and His power toward them is a direct appeal for them to grasp their “new identity in Christ.” This understanding is foundational for the call to unity and a worthy walk that will follow, as one cannot live out the calling without first understanding the immense spiritual realities upon which it is based.

How Does This Text Point to Christ?:

This prayer, while directed to the Father, is thoroughly Christ-centered. Paul prays to “the God of our Lord Jesus Christ,” immediately rooting his prayer in Christ’s unique relationship with the Father. The believers’ “faith” is explicitly “in the Lord Jesus.” The hope, inheritance, and power they are to know are all realities secured by and experienced through their union with Christ. He is the one through whom the calling comes and in whom the inheritance is found.

Summary:

Hearing of the Ephesians’ faith in Jesus and their love for fellow believers, Paul responds with ceaseless thanksgiving and prayer. He petitions God the Father to grant them a spirit of wisdom and revelation so they might know God more intimately. Specifically, he prays for the eyes of their hearts to be enlightened to comprehend three profound truths: the glorious hope to which they have been called, the immense value they represent as God’s own inheritance, and the immeasurable divine power that is at work on their behalf.

Be Intentional: 

This week, make Paul’s prayer your own. Pray specifically for the “eyes of your heart to be enlightened” to know God better, and to grasp the hope, inheritance, and power He has given you.

Follow Paul’s example: Identify a specific believer or a group in your church and pray Paul’s prayer from verses 17-19a for them by name.

Ask Yourself: 

When I pray for myself or others, do my requests reflect Paul’s primary desire—for a deeper, more intimate “knowledge of him” (v. 17)—or do I focus mostly on changing my circumstances?

Of the three realities Paul wants us to know (our hope, our inheritance, His power), which one feels the most abstract or distant to me right now?

Why might that be? How does believing that I am part of God’s “glorious inheritance” change how I view my own worth and purpose?
