Read Matthew 13:10-23
Only the "good soil" is able to bear fruit from the "word of the kingdom" that is sown. That is because there is a vital union with Christ and the efficacious work of the Holy Spirit upon the soul. Are you abiding in Christ, and can you see the gracious fruit of faith, repentance, grateful worship, and the fruit of the Holy Spirit in your life, and maturing in your life? These are the visible signs of a soul that has been prepared by the Holy Spirit to receive God's Word.
