Number 1 in the Bible
The number 1 represents unity. When there is one, there is no division. Everything is in harmony. As a cardinal number it denotes unity, as a cardinal number it denotes primacy. In Deuteronomy, the Lord says, “Hear O Israel, the Lord our God is one Lord” (Deuteronomy 6:4). Jesus quoted this Scripture when he said, “The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord” (Mark 12:29).
Sometimes God is called the Holy One. “Thus says the Lord, your Redeemer, The Holy One of Israel: I am the Lord your God, Who teaches you to profit, Who leads you by the way you should go” (Isaiah 48:17). Jesus said the first and greatest commandment was “You shall love the Lord your God with all your heart, and all your soul, and with all your mind” (Matthew 24:37). He was quoting Deuteronomy 6:5.
God is the first (and the last). “Thus says the Lord, the King of Israel, And his Redeemer, the Lord of hosts: “I am the First and I am the Last; Besides Me there is no God” (Isaiah 44:6). Likewise, John recorded the words of Jesus by an angel, “I am the Alpha and the Omega, the Beginning and the End, says the Lord, who is and who was and who is to come, the Almighty” (Revelation 1:8). Elohim is the one and only God. There is no one like Him.
“Jesus is the image of the invisible God, the firstborn over all creation. For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist. And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the pre-eminence” (Colossians 1:15-18). Jesus Christ is called the first of the first fruits of those who have died and been resurrected back to eternal life in an immortal body (1 Corinthians 15:20-21).
