When Jesus talks about the 'heart,' what do you think He means? It's more than just feelings – it's the deepest control center of our lives.
Jesus reveals a profound truth here: the real source of our actions, both good and bad, isn't external circumstances, but our internal core. The 'heart' in Scripture isn't just about emotions like sadness or joy.
The Core of Being
It refers to the seat of our will, intellect, desires, and motivations. It's the 'inner man,' the deepest part of who we are. When the commentators speak of the 'heart' being 'wicked' and 'desperately so' (Gill), they're pointing to this fundamental corruption in our fallen nature.
The Origin of Action
Jesus is saying that our outward actions are merely the overflow of what's already happening within. The list that follows – evil thoughts, sexual immorality, theft, murder – are not random occurrences. They are the natural fruit of a heart that is estranged from God. As Henry puts it, 'A corrupt fountain sends forth corrupt streams.'
