"And when the Gentiles heard this, they began rejoicing and glorifying the word of the Lord, and as many as were appointed to eternal life believed." (Acts 13:48 ESV).
I am thankful to God that evangelism is not a man-centered duty or field of labor. It is one that is empowered by His Holy Spirit (Acts 4:31), and is rewarded with joy as the word of the Lord is glorified, since He had caused them to believe who had been "appointed to eternal life." Praise God that we can pray and labor to evangelize a world which hates the light (John 3:19-20), for some will believe, because they must believe and be saved, since God is ever faithful to His own promises (Genesis 12:1-3)! "...and in you all the families of the earth shall be blessed."
