Read Ephesians 3:14-21
3:14 For this reason I bow my knees before the Father,
3:15 from whom every family in heaven and on earth takes its name.
3:16 I pray that, according to the riches of his glory, he may grant that you may be strengthened in your inner being with power through his Spirit,
3:17 and that Christ may dwell in your hearts through faith, as you are being rooted and grounded in love.
3:18 I pray that you may have the power to comprehend, with all the saints, what is the breadth and length and height and depth,
3:19 and to know the love of Christ that surpasses knowledge, so that you may be filled with all the fullness of God.
3:20 Now to him who by the power at work within us is able to accomplish abundantly far more than all we can ask or imagine,
3:21 to him be glory in the church and in Christ Jesus to all generations, forever and ever. Amen.
What does it mean for you to be 'strengthened in your inner being'? The roots of the strength you need are in Christ's love for you.
Simply pray verses 16-19 making it a prayer for yourself.
