The church of God is founded only upon God's light of truth (see 1 Timothy 3:15), because God is only the Author of light, goodness and truth (see Genesis 1:3-4; Matthew 19:17; James 1:17).
Ang iglesya ng Dios ay nakabatay lamang sa liwanag ng katotohanan ng Dios (tingnan ang 1 Timoteo 3:15), sapagkat ang Dios ang tanging pinagmumulan ng liwanag, kabutihan at katotohanan (tingnan ang Genesis 1:3-4; Mateo 19:17; Santiago 1:17).
