Does someone have to explain the Scriptures to an unbeliever for them to believe?
No, it is not mandatory, but usually someone must explain the Scriptures to an unbeliever and bring him to the point of belief and understanding. God providentially sends proclaimers, yet the Lord Himself must open the heart, as with Lydia in Acts 16.
Les explains that it is not mandatory, but usually someone has to explain the Scriptures to an unbeliever and bring him to the place where he can believe and understand. He asks how they can hear unless God providentially sends someone to proclaim it, affirming that it takes God's providence, power, and the working of the Holy Spirit. Les points to Acts 16:14 and Lydia, a religious woman whose heart the Lord opened—not Paul or Luke—so that she could believe.
