1 Thessalonians 2:1
For yourselves, brethren, know our entrance in unto you, that it was not in vain:
Note 1 at 1Th 2:1: Paul's ministry to the Thessalonians was not "in vain." The Greek word for "vain" is "KENOS" and literally means "empty...fruitless, without effect" (Thayer's Greek-English Lexicon). This could be interpreted as Paul's coming to the Thessalonians was successful, or accomplished a purpose. The New English Bible translates this verse, "You know for yourselves, brothers, that our visit to you was not fruitless."
