The heart of the beginning of the apostle Paul’s prayer in Ephesians 3 is that every Christian would be committed to and diligently exercise the Christian disciplines that God has given His people—specifically prayer.

Sanctification, or spiritual growth, is a major theme in the New Testament. The apostle Paul understood the importance of growth in the Christian life, which is why he prayed for such growth in Ephesians 3.

The Bible teaches that the Christian life and the pursuit of sanctification are works of God that require dedication on the Christian’s part. And just like the physical body grows slowly over time, the believer’s spiritual life happens in the same way.

In Ephesians 3, the apostle Paul prays that the Ephesians—and all true Christians and all true churches of all ages—will understand the depth of the love of God in Christ Jesus. For us, as Christians, we have come to know God’s love in Christ because Christ died of our sins and has given us new life.

The apostle Paul believed that understanding the love of God was a non-negotiable part of the Christian life. He understood God’s love to be foundational, and in Ephesians 3, he prayed that there wouldn't be a single Christian who would neglect such a reality.
