1:1-8 All true Christians are brethren one to another. Faithfulness runs through every character and relation of the Christian life. Faith, hope, and love, are the three principal graces in the Christian life, and proper matter for prayer and thanksgiving. The more we fix our hopes on the reward in the other world, the more free shall we be in doing good with our earthly treasure. It was treasured up for them, no enemy could deprive them of it. The gospel is the word of truth, and we may safely venture our souls upon it.

Then what is asserted is not that the Gospel has been preached in all the world, but that it is bearing fruits of righteousness, and (like a tree growing at the same time that it is bearing fruit) growing in numbers of its converts in, or throughout, all the world.
