# Because of this love

"Because the Holy Spirit has enabled you to love other believers"

# we heard ... we have not stopped ... We pray

The word "we" does not include the Colossians. 

# from the day we heard this

"from the day Epaphras told us these things"

# that you will be filled with the knowledge of his will

Paul speaks of the Colossian believers as though they were containers. Alternate translation: "that God will fill you with what you need to know so that you can do his will"

# in all wisdom and spiritual understanding

"so that the Holy Spirit will make you wise and able to understand what God wants you to do"
