The message(Colossians:1)

hello guys i havent doing by qt for like 2 days because i was dying with
school stuff sorry but i will do them

Colossians: 1
I was little lost in the beginning but i kept reading..
Paul begins with his thanksgiving and prayers. He prayed that the Epaphras
they be filled with the knowledge of God's will, walk in a manner
worthy of the Lord...
What was Paul's goal in preaching Christ?
anyone know the answer
??
