28. Everything said so far can be found in many places in the Word. I may cite only the following few.

The Word tells us that no one can be focused on doing good and doing evil at the same time, or - which amounts to the same thing - with respect to our souls we cannot be in heaven and in hell at the same time. It tells us this by saying,

No one can serve two masters; for you will either hate the one and love the other or hold to the one and despise the other. You cannot serve God and Mammon. (Matthew 6:24)

How can the things you say be good when you are evil? Out of the abundance of the heart the mouth speaks. Good people out of the good treasure of their hearts bring forth good things, and evil people out of the evil treasure bring forth evil things. (Matthew 12:34-35)

A good tree does not bear bad fruit, and a bad tree does not bear good fruit. Every tree is known by its own fruit. People do not gather figs from thorns or harvest grapes from a bramble bush. (Luke 6:43-44)
