Oh, the depth of the riches and wisdom and knowledge of God!
How unsearchable are his judgments and how inscrutable his ways!
(Romans 11:33 ESV)
Great is the LORD, and greatly to be praised,
and his greatness is unsearchable.
(Psalm 145:3 ESV)
Such knowledge is too wonderful for me;
it is high; I cannot attain it.
(Psalm 139:6 ESV)
Great is our Lord, and abundant in power;
his understanding is beyond measure.
(Psalm 147:5 ESV)
And though there is no ultimate finality in knowledge, there is also no futility. We can know Him - we must! It is a matter of life or death.
And this is eternal life, that they know you the only true God, and Jesus Christ whom you have sent.
(John 17:3 ESV, emphasis added)
And we know that the Son of God has come and has given us understanding, so that we may know him who is true; and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life. Little children, keep yourselves from idols.
(1 John 5:20-21 ESV, emphasis added)
May Paul's prayer be ours, to know the unknowable...
For this reason I bow my knees before the Father, from whom every family in heaven and on earth is named, that according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith—that you, being rooted and grounded in love, may have strength to comprehend with all the saints what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, that you may be filled with all the fullness of God.
(Ephesians 3:14-19 ESV, emphasis added)
