Ephesians 3:14-16. For this reason I bow my knees to the Father of our Lord Jesus Christ, from whom the whole family in heaven and earth is named, that He would grant you, according to the riches of His glory, to be strengthened with might through His Spirit in the inner man…
Your spirit is what Paul refers to as your “inward man.” (2 Cor 4:16). Peter refers to your spirit as the “hidden man of the heart.” (1 Peter 3:4). Since we serve God with our spirits (Rom 1:9), we want our spirits to be strong!
That’s why Paul prayed for the believers at Ephesus that God would grant them to be strengthened with might by His Spirit in their inner man.
In his prayer, Paul said that by virtue of the believers at Ephesus being strengthened by the “dunamis”-power of the Holy Spirit in their inward man, Christ would dwell in their hearts through faith; they would be rooted and grounded in love; they would be enabled to comprehend and know the breadth and length and height and depth of the love of Christ which surpasses all knowledge; and they would be filled up to all the fullness of God Himself!! (Eph 3:14-21).
We can pray that same prayer for ourselves and for other believers! Hallelujah!! When you ask God anything according to His Word, the Bible says that He hears you and that you know that you have the petitions that you have desired of Him. (1 John 5:14-15).
Not only that, but your spirit grows and develops the same way your body does—through proper diet and exercise.
Meditating on the Word of God and praying in tongues is to your spirit what food and exercise are to your body. Together they will cause you to be strengthened with might by the Holy Spirit in your inner man!
