2 Thessalonians 2:2 not to become easily unsettled or alarmed by the teaching allegedly from us—whether by a prophecy or by word of mouth or by letter—asserting that the day of the Lord has already come.
Words of encouragement to the church at Thessalonica at the time to try and persuade them not to give up on things when the going gets tough.
Jesus made no excuses about life being tough as a Christian: but He did promise us comfort and joy, even during those tough times.
Christ has promised us He will return. That is our hope and what we have to look forward to. Don’t allow the smaller things in life to get you down.
