Luke 6:44-49

44 Each tree is recognized by its own fruit -- figs aren't picked from thorn bushes, nor grapes from a briar patch.

45 The good person produces good things from the store of good in his heart, while the evil person produces evil things from the store of evil in his heart. For his mouth speaks what overflows from his heart.

46 "Why do you call me, `Lord! Lord!' but not do what I say?

47 Everyone who comes to me, hears my words and acts on them -- I will show you what he is like:

48 he is like someone building a house who dug deep and laid the foundation on bedrock. When a flood came, the torrent beat against that house but couldn't shake it, because it was constructed well.

49 And whoever hears my words but doesn't act on them is like someone who built his house on the ground without any foundation. As soon as the river struck it, it collapsed and that house became a horrendous wreck!"
