The Greek logos means ‘word’, ‘reason’ or ‘plan’. The Greek philosopher Heraclitus, who lived around 500 years before Jesus, used the term to mean ‘the divine reason’, which brought everything into existence. In John 1:1-5, the apostle John draws on this term, but he makes it clear that there is more to this than just a divine ‘thought’ - the logos or Word is a person of the Trinity. John explains that God’s Son, who would be born as Jesus Christ, is the divine Logos. He is the eternal Word, the one through whom God created the universe, and the one who makes sense of all things as He reveals Himself to us. Jesus is the reason for everything.
