Gathering of the saints needs to be one of the top priority of Christ followers, in fact it is crucial and essential to the faith! For the good of their own soul, for the mission of Christ, and for the health of local congregation.
Discipleship doesn’t happen apart from the context of local church. There is no such thing as a solo-discipleship as it’s a foreign idea. We can’t become the Christian we are meant to be by being alone with God.
