How do we know that God's grace enables us to be good ground hearers?

According to Scripture, particularly in 1 John 2:27, it is only through God's grace and the anointing of the Holy Spirit that a person can be considered a good ground hearer. The unction, or enablement, from the Holy One allows believers to discern spiritual truths that are otherwise foolishness to the natural man (1 Corinthians 2:14). It is not through personal merit or human disposition but purely through divine intervention that one can respond positively to the gospel and embrace God's truth in their hearts.
