Luke 8:8, 15, 18

And some fell into good soil, and grew up and produced a crop a hundred times as great.” As He said these things, He called out, “He who has ears to hear, let him hear and heed My words.”

But as for that seed in the good soil, these are the ones who have heard the word with a good and noble heart, and hold on to it tightly, and bear fruit with patience.

So be careful how you listen; for whoever has [a teachable heart], to him more [understanding] will be given; and whoever does not have [a longing for truth], even what he thinks he has will be taken away from him.” [Matt 13:12; 25:29; Mark 4:25]
