Colossians 1:9

For this cause we also, since the day we heard it, do not cease to pray and make request for you, that ye may be filled with the knowledge of his will in all spiritual wisdom and understanding.

In this and verses following the limitless aspirations of Paul's prayers for fellow-Christians is observable. Note the unlimited nature of this request:

He asks that they may be filled with the knowledge of God's will in all spiritual wisdom ... unto all pleasing, bearing fruit in every good work, and increasing in the knowledge of God![19]

It should be particularly observed that the knowledge here prayed for is the knowledge of God's will, as Barry expressed it, "Not speculation as the the nature of God, or emanations from Deity, or even as to reasons of God's mysterious counsels."[20] Above everything else people need to know what the will of God is, and having learned it, to do it to the best of their ability.
