How do we know the interpretation of the parable of the sower is true?

The interpretation of the parable of the sower is validated by Jesus when He explains it in Mark 4:10-20. He clearly delineates the types of soil and their corresponding responses to the Word of God. This divine revelation assures us of its truth, as the Lord delineates the distinctions between those who hear the gospel with different levels of receptivity. The presence of divine authority in Jesus' explanation guarantees the reliability of the interpretation and helps us understand the mystery of the kingdom of God. The Holy Spirit aids believers in grasping these truths.
