Begin by reading and meditating on Philippians 1:20-26.
And recall last week Monday’s post on living short.
…While you shouldn’t presume on the grace of God to give you tomorrow, it is not foolish to work today in anticipation of tomorrow. However, tomorrow can only be prepared for by making the most of today. So while you must make the most of the day God has given you, it is important to look ahead to where your day might lead you and others down the road. You are never just living for the moment. You are living for eternity, and your life has the potential to prove fruitful not only for yourself, but also for many others.
To live long means that you are thinking into the future for the well-being of yourself and others. It is good to ask if you have a plan in place to grow your family in the faith, preparing them for the potential hardships ahead that you are most likely to lead them through.
…Consider your calling, and then determine what it means for you, as a Christian, to fulfill your calling in such a way that will glorify God, serve his mission, and demonstrate grace to the world.
