We pray for inner strength (3:16-17)
16 that according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being,
17 so that Christ may dwell in your hearts through faith—that you, being rooted and grounded in love,
Ephesians 1:13-14 ESV
13 In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit,
14 who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.
2 Corinthians 4:16-18 ESV
16 So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day.
17 For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison,
18 as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.
