Renowned theologian and seminary professor Wayne Grudem spoke as a guest speaker at Mars Hill Church in Seattle, Wash., for their "Best Sermon Ever" series, highlighting the importance of guarding one's hearts as Christians, based on Proverbs 4:23.
"Keep your heart with all vigilance, for from it flow the springs of life," Grudem began by reading the verse, and explained that it talks about protecting, guarding, caring for your heart.
Biblical reference to the heart "includes all of your deepest moral and spiritual convictions, along with your feelings and emotions, especially your deepest moral and spiritual convictions in relationship to God," said Grudem, the general editor of the ESV Study Bible, on Aug. 25.
In this verse, "God is saying basically that the inward spiritual and moral life that you have will determine the course of your life and ministry, whether it will be a life that knows God's favor and blessing or not," added Grudem, the author of Systematic Theology: An Introduction to Biblical Doctrine.
Grudem shared three things in his sermon: what it is to keep your heart, why you should keep your heart, and how you keep your heart.
