28. Everything we have said so far is taught by the Word in many places, of which we will cite only the following.

The Word teaches that no one can be governed by good and at the same time by evil, or in other words, that no one can be with his soul in heaven and at the same time in hell. It teaches this in the following passages:

No one can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon. (Matthew 6:24)

How can you speak good things when you are evil? ...out of the abundance of the heart the mouth speaks. A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things. (Matthew 12:34-35)

...a good tree does not bear bad fruit, nor does a bad tree bear good fruit. ...every tree is known by its own fruit. For men do not gather figs from thorns, nor do they gather grapes from a bramble bush. (Luke 6:43-44)
