making the best use of the time

Today, i read this in "The Reformed Pastor" by Richard Baxter, and it ties in nicely with having also read Colossians 4:5 :

"Alas! all our business in this world is to get well to heaven; and God hath appointed us to be guides to His people; to help them safe thither. If this be well done, all is done; and if this be not done, we are for ever undone. The Lord knows how short a time you and I may be together; and therefore it concerns us to do what we can for our own and your salvation before we leave you, or you leave the world. All other business in the world is but as toys and dreams in comparison of this."
