2 - Do we think more about when things will happen instead of how we can be prepared for them?
I think we are all guilty of this. I know I like to know when something will happen, start or end and it can cause me stress if I don't know which takes my mind off the important stuff. Reading that I think if I focus more on the event or being prepared for it I would cope better. The same as focussing on being with God and ready for Jesus return whenever it is.
I came across this in a commentary on 1 Thessalonians that I find helpful - and challenging:
Perhaps most importantly, Paul reminds the readers repeatedly that the work of God begun in them in Christ will not be complete until Christ returns. They can therefore look forward to his return with great expectancy, remembering that even death itself will then be utterly defeated, and living each moment in faithfulness as they await the fulfillment of their relationship with Christ.
