When Charles McMullan was Moderator of the Presbyterian Church, he said at his 2018 installation and then again on the night he handed over to William Henry that the Christian life rises and falls on the devotional. He was very clearly stating how important he felt the personal devotional is in Christian growth. I agree with him, I think the traditional quiet time, devotional, personal bible reading and prayer; whatever name you want to give it, plays a central role in the Christian life. When I look back over my life, recent and long ago, I can see the ups and downs in my walk with God clearly linked to times when I was diligent in my own personal devotions and when I was careless with them. What is interesting is that as we come to Ephesians chapter 4: 1-16 Paul answers this question and his primary concern is not the personal, but the corporate. In other words, it is not what we are doing on our own that Paul addresses, but how we live, or fail to live, together as one people. For Paul, the community of believers was paramount, and it is this sense of community he addresses.
