In the Bible, the heart is not just the source of our emotions. It is the command center of our entire being that directs all of our thoughts, words, and actions. Among many important things to pray for, Paul understood that praying for the hearts of his hearers was his greatest pastoral priority. Only hearts that are increasingly transformed by the indwelling love of Christ will grow, serve, and multiply as God intends. God calls us to know the depth of His love for us in Christ and to pray that others might know it as well.
