In this message, Terry Timm uses the metaphor of life as a marathon to explore the stages of the "critical journey," a process of spiritual formation with six distinct stages, including the inevitable experience of hitting a "wall." He discusses the importance of recognizing where one is on this journey and the invitations that each stage offers, emphasizing God's omnipresence and the role of grace throughout. Ultimately, Terry encourages listeners to embrace their current stage, seek community support, and rely on God's grace to navigate their spiritual path.
