Overview:
- Main metaphor: the history of light bulbs (Edison, halogen, CFL, LED) is used to illustrate spiritual dimness and the need for renewal.
- Covenant renewal is presented as a communal, repeated practice (Josiah, Wesley) that restores relationship with God and shapes faithful living.
- Practical guidance: make spiritual commitments specific, measurable, attainable and give yourself grace when you fail.
- Outreach emphasis: Epiphany and the Magi remind the community to invite outsiders, welcome the stranger, and engage those on the margins.
