Take care what you listen to and what you do with it.
He also told them, “Take care what you hear. The measure with which you measure will be measured out to you, and still more will be given to you. To the one who has, more will be given; from the one who has not, even what he has will be taken away.” Mark 4:24-25
“Take care, then, how you hear. To anyone who has, more will be given, and from the one who has not, even what he seems to have will be taken away.” Luke 8:18
We are evaluated based on what we know. We are accountable to apply what we know and to share it with others. Failure to do so is a serious matter. From those to whom much has been given, much shall be required. (Luke 12:48) This is a valid principle in responsibilities and rewards, such as in the parable of the talents. It is also valid in terms of punishment. (Luke 12:48)
Our own faithfulness is important. It is also good stewardship for us to invest in others who are faithful with what they learn and receive. We are not doing people a favor if we continually “pour into them” if they are not faithfully applying and sharing what they have already learned.
