Lesson 1 · Upper Room: Growing Deeper

The Oneness of God

The foundation of all truth is that there is one God. He is not three separate persons, but one God who has revealed Himself to us in different ways.

Key verse

“Hear, O Israel: The Lord our God, the Lord is one!”

Deuteronomy 6:4 · NKJV

One God

The Scriptures declare that God is one. “Hear, O Israel: The Lord our God, the Lord is one!” (Deuteronomy 6:4). “I am the First and I am the Last; Besides Me there is no God.” (Isaiah 44:6)

God manifest in flesh

This one God came to us in His Son. “God was manifested in the flesh” (1 Timothy 3:16), for “in Him dwells all the fullness of the Godhead bodily” (Colossians 2:9). Jesus said, “He who has seen Me has seen the Father.” (John 14:9)

Father, Son, and Spirit

God is Father in creation, Son in redemption, and Holy Spirit dwelling in us — one God, not three. “I and My Father are one.” (John 10:30)
