Charles Spurgeon Commentary 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," — Colossians 1:9 (ASV)

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

If you have the graces of the Spirit, it is important that they should be deepened, that they should grow through being fed with divine nourishment. What the water is to the plant, making it develop itself further, that is the knowledge of God's will to our gifts and graces; they grow and become fruitful through an increase in the knowledge of God.

For this cause we also, since the day we heard it, do not cease to pray for you and to desire that you might be filled with the knowledge of his will in his wisdom and spiritual understanding, (Colossians 1:9).

See! The apostle asks for them something more even than faith, and hope, and love—that they might be filled with the knowledge of his will in all wisdom and spiritual understanding. This shows what a valuable thing it is to know and understand the will of God.
