The logos was in the beginning. John the apostle writes in John 1:2 that the logos was in the beginning with God. We have seen in John 1:1 that the very existence of Jesus Christ was before all of Creation. There was nothing before Creation except God in Three Persons, the Trinity: the Father, the Son, and the Holy Spirit. And this logos we have seen is very God! His Deity is that of the God of the Bible, the God of the heavens. He was, and is, and evermore shall be!
John links together into this one phrase two of the ideas already stated in John 1:1: in the beginning He was with God. Later in time–as we shall see–Jesus Christ came to be with man through His Incarnation (A.T. Robertson, Word Pictures in the New Testament). John is reiterating that Jesus Christ pre-existed before His Incarnation. He is Personal. He is Deity. He is God. There is nothing in His very nature, essence, or substance that is not God. He is very God!
The assumption of the Bible in Genesis 1:1 is out of nothing God created everything. This means there was no thing that He used to create all that we see, touch, taste, smell, and feel. All things, as we continue to discover the mysteries of the air, the seas, of the planets, the universe came into being when God created all of these things. John says that all things came into being through Him [the logos, Jesus Christ], and apart from Him nothing came into being that has come into being (John 1:3). While we see in the beginning God created the heavens and the earth (Genesis 1:1), John states emphatically that the logos–Jesus Christ–is the One who created all things. Creation, as presented by John, is not something that existed prior to Jesus Christ’s act of creating, but, rather, came into being when Jesus Christ created all things.
Jesus Christ is the intermediate agent in the work of Creation. While the Hebrews would understand the Creation as beginning out of nothing by God, John now relays to them this revelation: Jesus Christ is the Creator! The Greeks are also given this explanation: it is not logic that created or even sustains all things, but rather it is the logos who is Jesus Christ who created and even sustains all things. And His sustaining of all things is not something that is static. Rather, it is a dynamic sustaining of all things. He is ultimately the One who is bringing all things to fruition for His own glory and honor. The logos is causing all things to progress in His Creation.
Jesus Christ was in the beginning, before anything was created, and all things have come into being through Him. Apart from Jesus Christ, nothing has come into being–it has not existed–until He created it.
