It is a common assumption that a person's good works will get them into Heaven.
Undoubtedly, the most important thing to remember is your time is not your own. Yes, we live in a time when people believe that you can and you should do exactly what you want, but all time belongs to God. So make sure your time is first dedicated to getting His work accomplished.
Make it a point to choose the right backer, make your investments wisely, and do the work of the Lord which guarantees exceeding and abundant eternal benefits.
God is using people to accomplish His work, of saving souls, but we have to remember that it is not us doing the work. It's God using our vessel.
