Colossians 1:10 so that you may live a life worthy of the Lord and please him in every way: bearing fruit in every good work, growing in the knowledge of God,
Paul knew God had told him to go out and tell many different people about God; and so he did so, willingly.
His prayers for the people he met and taught were not that they would give up everything and come to him to be taught, but he would be able to go out to them and God would fill them with the right knowledge and wisdom.
Sometimes we have to trust others to do what we know has to be done because we cannot be in all places at the same time – that is God’s realm and what He is going to do as long as we sow the seeds.
