I’ll admit my bias, I’m a fan of group life.
In my observation, the best and most enduring stories of life change are connected to some form of small group experience.
Christianity was never designed to be a journey taken alone. In fact, I don’t believe you can live your faith journey to its fullest potential by yourself.
You can know Jesus as Savior, but you will not likely experience the fullness of growth and maturity that you are designed for, if you do it on your own.
