And the one on whom seed was sown on the good soil, this is the man who hears the word and understands it; who indeed bears fruit and brings forth, some a hundredfold, some sixty, and some thirty (Matthew 13:23). The ultimate barrier to salvation is unbelief, and anyone willing to receive the gospel on Christs terms proves he or she is good soil. God honors the humble faith of receptive hearers and opens their spiritual ears, minds, and hearts, allowing them to understand the gospel.
