The answer
St. Ambrose says, “The Apostle found nothing better to wish us than this, as He himself said: ‘We cease not to pray and make request for you that you may be filled with the knowledge of His will, in all wisdom and spiritual understanding, walking worthily of God.’ He taught, then, that this was the will of God, that rather by walking in good works and words and affections, we should be filled with the will of God, Who puts His Holy Spirit in our hearts.”95
