God calls people into different works. In the midst of this diversity, a common thread unites all the work—men ought to do all they do to the glory of God.
How would making your motive match the Lord's motive change how you approach the Christian life (from witnessing to praying to Bible reading and so on)?
In the presence of others, Paul carefully behaved himself in such a way to bring glory to God. For example, when Paul was in the presence of the believers at Thessalonica, he was gentle, “even as a nurse cherisheth her children.” He laboured “night and day” because he “would not be chargeable” to the believers. Paul conducted himself in such a godly way that he had no problem suggesting that the believers themselves were witnesses of “how holily and justly and unblameably” he had behaved among them. Paul thought his testimony was so important that he would rather personally suffer than bring any reproach or blame upon himself or the work of God.
