There are many things we choose to invest time in doing, but we should invest most of our time in what matters for eternity. In 1 Timothy 4:8 Paul says to Timothy, For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come. While physical well-being is important, we should spend most of out time working on things that have an impact towards God’s eternal kingdom. These bodies will one day fail, but our Spirit will live on forever.
