Ecclesiastes 1, 2 and 3 is a consideration of the purpose of life. Basically Solomon has discovered that if you are doing things to make a mark on the world it will only lead to disappointment because sooner or later you will be forgotten. If you are doing things strictly for your own enjoyment it will also lead to disappointment because in the end its value becomes lessened. If you are doing things to pass them on to others it will lead to disappointment because the future generations may not appreciate what you have done. Nothing has purpose without God being involved in it for pleasure only comes as a gift from God. Nothing will last forever, it will all pass away so its value must be enjoyed in the present.

2 Thessalonians 2 deals with some questions the Thessalonians have regarding when Christ is returning. There apparently are some who are saying the He has already come. Paul states that this is just a manifestation of Satan who is trying to confuse them.  He encourages them to stick with the things they have been taught and stand firm.
