We Believe in Deuteronomy 6:4 which says "Hear O Israel, the Lord our God, the Lord is one." God is Echad (one) and He exists forever in three persons: Father(Abba), Son(HaBen), and Holy Spirit (Ruach HaKodesh) - Romans 8:14-17.
We believe in His Son, Yeshua Ha Mashiach (Jesus the Messiah), who was and is and is to come. His name means salvation. He came into this world born of a virgin in full Deity and is worshiped as God, having existed eternally. Isaiah 9:6-7; Matthew 28:18-20; Philippians 2:5-11; Colossians 1:15-19; Revelation 3:21, Hebrews 1:, Revelations 4:8, and 5:5-14. He is the promised Messiah of Israel Isaiah 9:6-7; 11:1; Daniel 9: 20-26; Isaiah 53; John 1:17, 40-41, 45, 49; Mark 8:29. He is the root of Jesse, the Lion of Judah, the offspring of David, the Bright and Morning Star, the Lamb of God (I Corinthians 5:7; Revelation 5; John 1:29).
