We need to pray for motivation to read the scriptures and also for the guidance of the Holy Spirit. We need to delight in the scriptures; that is, enjoy the word of God and feel the love offered to us by the message it gives us. We need to not just let the letters pass before our eyes, because the idea is for us to fall in love with this marvelous gospel.
Each time you search the scriptures, you will learn more, and through them you can come to know the will of our Heavenly Father. He often answers our prayers through the standard works of the Church. When we feel peace and receive inspiring thoughts, we can know that they come from Heavenly Father through the Holy Ghost (see D&C 8:1–3).
