Individuals are responsible for their own spiritual growth. After all, the leader and group can't grow for them. So, here are three things they can do to maximize their own growth during the life of a group.
1. Stay engaged. This just means choosing to be involved in the life of the group. The best way to do that is to show up to group meetings, socials, service projects, and other events. Join in by actively participating in the conversations that happen in group, as well as take on some of the tasks (hosting meetings, bringing snacks, emailing prayer requests, etc.) that make group happen. And be real by letting the other members of the group know what's going on in your life. They can't offer encouragement and accountability unless you're real about what's going on with you.
2. Remain curious. Commit to discovering more about God, yourself, and the other people in your group. If you do that, you can't help but grow. To remain curious, ask questions. It helps you see other peoples' perspectives, and that will help you to grow.
3. Take a step. Growing spiritually isn't just about learning more about God. It's about applying what you learn about God in the day-to-day details of your life. When what you learn affects your decision-making and how you behave, it grows your trust in God. And that growing trust is the definition of spiritual growth. That happens when you identify clear next steps for growth. Maybe you need to serve in a Sunday morning ministry environment. Maybe it's time to have a challenging conversation with a friend or colleague. Maybe you feel called to go on a mission trip, Or maybe you just need to start reading the Bible and praying on a regular basis. Whatever that next step is for you, once you identify it you need to follow through. And you're group can offer you encouragement and accountability as you make progress.
So the bad news is, no one can make another person grow. But the good news is every individual can take charge of their own spiritual growth. They'll need others' help as they grow because God has designed us to live in community. But no one has to wait around for someone to take action on their behalf.
