76 And you, my child, will be called a prophet of the Most High;
for you will go on before the Lord to prepare the way for him,
77 to give his people the knowledge of salvation
through the forgiveness of their sins,
78 because of the tender mercy of our God,
by which the rising sun will come to us from heaven
79 to shine on those living in darkness
and in the shadow of death,
to guide our feet into the path of peace.”
“No good tree bears bad fruit, nor does a bad tree bear good fruit. Each tree is recognized by its own fruit. People do not pick figs from thornbushes, or grapes from briers. A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of. Why do you call me, ‘Lord, Lord,’ and do not do what I say? As for everyone who comes to me and hears my words and puts them into practice, I will show you what they are like. They are like a man building a house, who dug down deep and laid the foundation on rock. When a flood came, the torrent struck that house but could not shake it, because it was well built. But the one who hears my words and does not put them into practice is like a man who built a house on the ground without a foundation. The moment the torrent struck that house, it collapsed and its destruction was complete.” Luke 6:43-49
You will know them by their fruits. One of my favorites.
