The condition of our hearts will determine how we are affected by the Gospel. We may harden our hearts and reject it or we can soften our hearts so that it will dwell with us and bring forth fruit in our lives.
The word of God will be found by those who seek it. The Scriptures can teach us how to obtain salvation and how to live as Christians. The more we study and meditate upon it the deeper we will understand it. And when we learn the commands of God we must be obedient to them.
