Luke 8:15
But that on the good ground are they, which in an honest and good heart, having heard the word keep it, and bring forth fruit with patience.

Learning takes time. Knowledge is power, and with Jesus inside you helping you study the bible you will bring forth fruit and your heart will change and grow. Guard your heart and make the word of God the final authority over what you believe. Don’t let the devil steal from you what you have gained in knowledge of God.
