You weren’t meant to go through life all alone. You were designed for community. More importantly, God wants to disciple you and to use you to disciple others. Small community groups are God’s Biblical model of working in your life and using you to work in the lives of others.

And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, for the equipping of the saints for the work of ministry, for the edifying of the body of Christ.
-Ephesians 4:11-12
