17 that the God of our Lord Jesus Christ, the Father of glory, may give to you the spirit of wisdom and revelation in the knowledge of Him,
“That” indicates the purpose of Paul’s prayer in verse 16.
the God of our Lord Jesus Christ,
The Lord Jesus Christ is subordinate to the Father. Jesus in His humanity has a unique relationship to the Father. Paul directed his petition in prayer to the Father, the one to whom the Lord Jesus prayed. He did not pray directly to the humanity of Christ.
the Father of [the] glory,
All glory belongs to the Father (Ac 7:2). “Glory” demonstrates the splendor of the Father’s attributes and work.
may give to you the spirit of wisdom
Paul prayed that the Father would give the Ephesian church “the spirit of wisdom and revelation.” Only God can give us a receptive attitude to His truth.
“Spirit” here is not the Holy Spirit but the attitude or disposition of wisdom and revelation. “Wisdom” gives insight about God.
“Revelation” unveils truth about God.
in the knowledge of Him,
If the believer carries the spirit of wisdom and revelation, he will know God better. “Knowledge” here is not abstract knowledge about objective facts but the knowing of God personally. The idea carries intimate knowledge of God’s person and work. The Greek word is full knowledge, insight knowledge, experiential knowledge.
Wisdom in knowledge about God is designed to produce our fellowship with Him on a solid basis.
A purpose of God is to know God and make Him known (Jn 17:3). Knowing God is progressive. It requires continual growth in knowledge about Him from the Word of God.
Many Christians settle for something far less. Some know facts of the Bible without having any sense of applying that knowledge to their experience. Knowing God and knowing about Him are different things. Knowing Him involves body, soul, and spirit; lock, stock, and barrel.
Raw enthusiasm is not adequate for spiritual growth. Unless we gain maturity in what God has revealed to us and have the wisdom to apply it to our experience, we will remain in spiritual childhood. It is not enough to have a spiritual bank account; we must examine our wealth to know what we have in Christ.
It is possible to be a biblical scholar and not allow biblical principles to reach the heart. Truth is one thing; truth applied is another.
We will never live long enough to know everything about God. Learning about Him is a life-long experience (Jn 17:3; Phil 3:10; 2 Pe 3:18). However, the more we study the Bible, the better we will know God. The longer we are married, the better we understand our mate.
