my heart was opened
Christ compares the word of God unto a seed saying he who receives the seed into good ground hears the word, understands it, and bears fruit. To receive the seed our hearts must be open (KJV Bible, Matt 13:23).
We must give place for the seed to be planted in our hearts. If we don’t cast it out by unbelief, it will swell and begin to grow and we will know it’s a good seed, “for it beginneth to enlarge my soul; yea, it beginneth to enlighten my understanding, yea, it beginneth to be delicious to me” (Book of Mormon, Alma 32:28).
