Be transformed by the renewal of your mind. A call to grow, be renewed, and become a blessing to the world.

“Do not be conformed to this world, but be transformed by the renewal of your mind.”
The Year of Transformation is a decision of the Sinode Godang 2024 in the HKBP Strategic Plan 2024 to 2028. Its theme is drawn from Roma 12:2, a call to be transformed by the renewal of the mind.
The word transformation comes from the Greek metamorphoo, which means metamorphosis. Spiritual transformation is more than a change of behavior. It is a renewal of the way we think so that we understand God's good and perfect will.
Through transformation, HKBP wants to become a church that is more energized, moves more nimbly, is better, is more beautiful, and becomes a blessing to the world.
