The task is odd, almost illogical. Well, it IS illogical.
This is part of Paul’s prayer:
18 may have power, together with all the Lord’s holy people, to grasp how wide and long and high and deep is the love of Christ, 19 and to know this love that surpasses knowledge—that you may be filled to the measure of all the fullness of God. (Eph. 3:18,19)
It’s like saying, “I want you to know something you can’t know… but you’ll know it when you realize it’s past knowing…”
Our call to partakers of the divine nature is immense. It is truly beyond the ability to put into a formula and “know.”
This is the boldness we need. We need the boldness to climb the mountain we can’t conquer. We can never fully know God, but why should that stop us from making the attempt?
