1 Thessalonians 1:5
5 because our gospel came to you not simply with words but also with power, with the Holy Spirit and deep conviction. You know how we lived among you for your sake.
“The gospel came ‘with power’; it had a powerful effect on the Thessalonians. Whenever the Bible is heard and obeyed, lives are changed! Christianity is more than a collection of interesting facts; it is the power of God to everyone who believes. What has God’s power done in your life since you first believed?” (Life Application Study Bible 2015)
