How do you know a love that surpasses knowledge?

Ephesians 3:16-21

The key words and themes in this passage are: pray, power, love, fullness, immeasurable. This is a prayer that Paul is praying for the church in Ephesus. He has one main request: that the church would receive power from the Spirit so that a) Christ may dwell in their hearts and b) they would be able to know a love that surpasses knowledge (or, to use Paul's other word picture, to measure a love that is without limit). The result of receiving this power and knowing this unknowable love is that the church will be filled with the fullness of God. In my own words; "I pray that you would know the full measure of Christ's love so that you would be filled with the full measure of God.
Paul repeats himself in this prayer. First, he prays that God would fill the church with power so that Christ may dwell in their hearts then he prays that the church would have power so that they would be filled to the measure of the all the fullness of God. The second time he just gets a bit more specific about what he wants the church to have power to do; to be able to measure the unmeasurable love of God. The two "ends" are the same: that Christ, in all his fullness, would dwell in the hearts of the church. The two ends are achieved in the same way: only by God giving the church power.
Paul continues this idea of power in the next verse: by God's power, he can do immeasurably more than anything I could ever imagine, including, but not limited to, filling the church to the measure of all the fullness of God. What this means is that when the church displays strength, it is a miracle in the sense that it is an act of God; when the church grasps, even for a moment, the limitless love of God, it is a miracle. For me, it means that I need to pray for more miracles. To answer the question I posed in the title: the only way that the church can measure the unmeasurable love of God is by a miracle. It will take a miracle for the church to know, experience and extend the unknowable love of Christ. Only God can make it happen. I need to pray that God would fill the church with power to stand firm in the face of temptation. Only God can make that happen. I need to be reminded that I am part of the church and equally dependent on God for his miracle in my personal live. I am reminded that whenever I don't sin, it's a miracle; that whenever I do something good and right, it is not by my strength or moral character, it's a miracle. God, I need more miracles!!
