Eph 1:17 NLT
asking God, the glorious Father of our Lord Jesus Christ, to give you spiritual wisdom and insight so that you might grow in your knowledge of God.
Paul’s Prayer
Paul is asking God to give to the Ephesian believers spiritual wisdom and insight.
We like Paul should be concerned with growing in spiritual wisdom and insight. The powers of this world have been very successful at making us focus on only the physical side of this life, the things we can see and touch. But the spiritual is the most important.
Result
Paul is praying that believers would grow in spiritual wisdom and insight, because it leads to greater knowledge of God. Not simply a head knowledge, but an experiential knowledge.
