For Reflection/Discussion: Revelation 3.20 is frequently used as an effective evangelistic tool to help unbelievers open their hearts to Jesus. To whom are these words actually addressed? While the letter is addressed to a lukewarm church, Jesus stands at the door and knocks, waiting for individual believers to open the door to him. In what way are you and your faith contributing to or detracting from the spiritual health and missional effectiveness of your church family? If everyone in the church attend the way you attend, prayed as you pray, give as you give, and serve as you serve would the church be better or worse for it? What are the most important thoughts, attitudes, and actions you are taking away from this week's message?
