stepTWO in our Growth Track is MEMBERSHIP. Why Membership? You grow where you are committed! Offered every month starting on the second Sunday of the month, our three-week Membership course unpacks the vision of Beltway Park, our core values, and our central beliefs. At the end of the third session (on the fourth week of the month), you are given the opportunity to complete the membership process by being interviewed by a member of our church leadership.
