"I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love, may have power together with all the saints, to grasp how wide and long and high and deep is the love of Christ, and to know this love that surpasses knowledge- that you may be filled to the measure of all the fullness of God."
Ephesians 3:16-19 (The prayer starts with verse 13 and ends with verse 21.)
I think Pam, at Grey Like Snuffie, where you'll find more ABCs, or can participate, has this passage in her sidebar or somewhere. I don't think we'll totally understand God's love until heaven, but we do get filled and have a grasp of it from time to time. God brings changes in our lives that change us to be more like him, and to draw us closer to Him. I am so thankful for God's love for me!
