Some Christians become so focused on what their individual calling from God on their lives are that they become paralyzed. They aren't sure what do to with their career, relationships, life that they are unable to do the things God calls every believer to do.
Wesley and TJ know that feeling. But that have each individually found that focusing on the universal callings God places on every believer has helped them find the ways God prepared for them to glorify them.
Wesley and TJ discuss on a few universal calling for believers each. Wesley focused on discipleship, family, rest, and service. TJ lists worship, love, study, and work.
These callings apply to every believer in every age of every church. But how they are fulfilled may be unique and personal.
