'Good News' in the Bible

Now when I came to Troas [See Acts 16:8], in order to preach the good news about Christ, and when a door [of opportunity] was opened to me in [the service of] the Lord [there],

[This is] so we can proclaim the good news [about Christ] even to areas beyond you [Note: Perhaps Paul here alludes to such places as Italy and Spain], and [thereby] not boast over what has [already] been done in someone else's field of service.
