We Can Know the Heart

Matthew 7:16 ""You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they?"

We cannot separate the act from the person. A thief cannot steal if they don't already have theft in their heart. The heart comes first then the act after. We have been taught we cannot know the heart of a person, but God has shown us how we will know it.

Matthew 15:19 For out of the heart come evil thoughts--murder, adultery, sexual immorality, theft, false testimony, slander. For out of the heart come evil thoughts--murder, adultery, sexual immorality, theft, false testimony, slander.
