It is right for me to feel this way about all of you, since I have you in my heart
Although an evangelist a church planter and an apostle, Paul was a pastor at heart. He carries all the people in his heart all the time. It is no exaggeration when Paul says that he prays for all of them all of the time. It was his passion for the local church that would consistently drive him to his knees.
We too can share that passion as we commit ourselves to pray regularly for the local church. Paul's reason for carrying them in his heart is their shared experience of God's grace. This shared experience causes Paul to long all of you with the affection of Christ Jesus.
Ask God to give you a passion for the local church that you too might share the affection of Jesus for the people whom he loves. Find a way to carry them in your heart through a journal or index cards or a bookmark or whatever works for you.
