Our church has been studying Mark Dever's What is a Healthy Church? (which I highly recommend), and he argues that the church's primary function is to increasingly reflect God's character as it is revealed in God's Word. One of the tasks we disciples must undertake is to make God's thoughts our thoughts. We are commanded in Romans 12:1-2 to be transformed by the renewal of our minds. What brings about this renewal?
Scripture. We must read God's Word in such a way that we understand and affirm what are God's thoughts and opinions, and then we must appropriate those thoughts and opinions. We must increasingly reflect God's character. How can we possibly do this unless we discover what God has revealed to us in his Word!?! We must spend time and effort reading our Bibles. We cannot merely breeze through God's Word and check a task off the list. What does Scripture reveal about me, and how do I need to change?
This is an urgent need in my life, and in yours. These are the words of eternal life (John 6:67-69).
