Who had to open Lydia's heart before she could comprehend what Paul spoke?
The Lord, in the person of the Holy Spirit, had to open her heart before she could comprehend what Paul spoke. This work of the Holy Spirit is necessary for every person to come to saving knowledge of the Gospel; He is omnipresent and approaches every soul.
Les explains that Paul was the proclaimer, but before this Jewish lady in Philippi could comprehend, the Lord had to open her heart, in the person of the Holy Spirit. That has never changed: every person who comes to a saving knowledge of the Gospel must have their understanding opened by a work of the Holy Spirit. Les notes the Holy Spirit is omnipresent and does not miss a soul, so no one can say the Spirit never approached them. He connects this to John 1:9, the true light that lighteth every man, through the omnipresent work of the Holy Spirit, and to Romans 1, that no one at the Great White Throne can say they never had a chance.
And a certain woman named Lydia, a seller of purple, of the city of Thyatira, which worshipped God, heard us: whose heart the Lord opened, that she attended unto the things which were spoken of Paul.
