Jesus Christ is the word of God.
The Bible is the word of God,and Jesus is the Word of God with a capital,and also it means God manifest in the flesh.
The word of God is Him revealing Himself to people by words written in a book,and the Word of God is Him revealing Himself personally by manifesting Himself in flesh and dwelling among humans and speaking to them by His Son,the man Christ Jesus.
Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
Joh 1:3 All things were made by him; and without him was not any thing made that was made.
Jesus is the beginning of the creation of God,and the firstborn of all creatures,even though the man Christ Jesus was not born until 4000 years later,for God calls things that have not happened yet,as though they already happened,which all the works were finished from the foundation of the world.
In the beginning was the plan of God to come in the future in flesh,and that plan was with God before He started creating anything,and that plan was God manifest in the flesh.
All things were made with the plan of God to come in flesh,and without that plan God would of not created anything He created,for Jesus is the reason creation is successful,forgiveness of sins,and eternal life,and to judge the wicked angels,and people.
Jesus the Word of God was before the written word was given to humans,for although God already had it planned to give His word in the beginning Jesus is the first plan He had before any other plan,although He already had it all planned in the beginning.
