Cease not to give thanks for you, making mention of you in my prayers; 17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him: 18 The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints, 19 And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power, 20 Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places, 21 Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: 22 And hath put all things under his feet, and gave him to be the head over all things to the church, 23 Which is his body, the fulness of him that filleth all in all.
For this cause I bow my knees unto the Father of our Lord Jesus Christ, 15 Of whom the whole family in heaven and earth is named, 16 That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man; 17 That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love, 18 May be able to comprehend with all saints what is the breadth, and length, and depth, and height; 19 And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God. 20 Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, 21 Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.
For this cause we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding; 10 That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God; 11 Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness; 12 Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light: 13 Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: 14 In whom we have redemption through his blood, even the forgiveness of sins: 15 Who is the image of the invisible God, the firstborn of every creature: 16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: 17 And he is before all things, and by him all things consist. 18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
These are great prayers to personalize. For example, the Colossians 1 prayer could start out, "I pray that I might be filled with the knowledge of His will..." For personalized versions go here: The Ephesian Prayers
