1 Thessalonians 2:1-6
v1-2: Opposition and suffering will not stop true and faithful gospel ministers from preaching the gospel. Paul reminds the Thessalonian Christians that "he was not discouraged either by the suffering he met with or by the opposition raised against him." The gospel of Christ has always been met opposition since it was first declared.
v3: One mark of a true gospel preachers is that they are what they appear to be. The message they preach will be "without deceit... not erroneous, nor a cleverly invented story," and the way in which they speak will be "free from deceit and trickery," not saying one thing but meaning another.
v4: All who are called to preach the gospel have been entrusted with this message. It does not belong to them, but to God, so "they must not dare corrupt" it and "they must.. make use of what has been entrusted to them, as God has allowed and commanded, knowing they will be called to account." It is God they are to please, not people, remembering that "God not only sees all we do but also knows our thoughts" too.
v5-6: Speech that flatters and greedy motives are two sins that preachers are tempted by and which they must avoid. They must not "aim to influence the affections of human beings by glorying in them and fawning over them," nor should they seek to make themselves "rich by preaching the Gospel."
