The light was never meant to stay hidden.

PHOS is an invitation to surrender, transformation, and proclamation—to embrace your role as an ambassador of Christ.

Three-dimensional hardcover edition of PHOS: Surrender, Transformation, and Proclamation
PHOS by Billy Zang

More than knowing the light. Living it.

What began as Billy Zang’s biblical search into the word phos became a call to a more complete surrender: to glorify Jesus with our words, align our lives with Him, and disciple new believers toward the same light.

PHOS challenges the church to move beyond knowledge alone and embrace the everyday work of proclamation.

  1. 01

    Surrender

    Release the life you control to the One who gives it purpose.

  2. 02

    Transformation

    Let every new act of obedience renew how you live and see.

  3. 03

    Proclamation

    Carry the light of the Gospel into the words and work of life.

Your vessel is the chamber from which the light of the Gospel is projected to pierce the darkness.

The power of change is not your deeds, it is the One you proclaim—Jesus!

Meet Billy Zang

Billy has served as a worship and evangelism pastor for more than 30 years. Through ministry, music, and now PHOS, he invites believers into a deeper life of surrender and Gospel proclamation.
