Mat 25:24-29 (NLT)
24 "Then the servant with the one bag of silver came and said, 'Master, I knew you were a harsh man, harvesting crops you didn't plant and gathering crops you didn't cultivate. 25 I was afraid I would lose your money, so I hid it in the earth. Look, here is your money back.' 26 "But the master replied, 'You wicked and lazy servant! If you knew I harvested crops I didn't plant and gathered crops I didn't cultivate, 27 why didn't you deposit my money in the bank? At least I could have gotten some interest on it.' 28 "Then he ordered, 'Take the money from this servant, and give it to the one with the ten bags of silver. 29 To those who use well what they are given, even more will be given, and they will have an abundance. But from those who do nothing, even what little they have will be taken away.

Pro 20:12 (NLT)
Ears to hear and eyes to see--both are gifts from the LORD.

Rev 2:29 (NKJV)
He who has an ear, let him hear what the Spirit says to the churches.

[Mat 11:15 (NKJV)
He who has ears to hear, let him hear!

Mar 4:23-29 (NLT)
23 Anyone with ears to hear should listen and understand." 24 Then he added, "Pay close attention to what you hear. The closer you listen, the more understanding you will be given--and you will receive even more. 25 To those who listen to my teaching, more understanding will be given. But for those who are not listening, even what little understanding they have will be taken away from them." 26 Jesus also said, "The Kingdom of God is like a farmer who scatters seed on the ground. 27 Night and day, while he's asleep or awake, the seed sprouts and grows, but he does not understand how it happens. 28 The earth produces the crops on its own. First a leaf blade pushes through, then the heads of wheat are formed, and finally the grain ripens. 29 And as soon as the grain is ready, the farmer comes and harvests it with a sickle, for the harvest time has come."

Luk 8:18 (NKJV)
Therefore take heed how you hear. For whoever has, to him [more] will be given; and whoever does not have, even what he seems to have will be taken from him."
