Luke 8:18
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.
Our growth depends on how much we are willing to believe. We will not hear what we need to know from the Word of God if we don’t think it is true, such as healing, finances, and forgiveness. If we close our hearts to the belief that God’s Word says we can be healed, we won’t, even though Jesus says healing is ours.
