What does it mean, when the Bible calls Jesus Christ the firstborn of all creation?
Jesus Christ is called the firstborn of all creation (see the Bible book Colossians 1:15) because, according to the Bible, he is the first creation of Jehovah God.
After we learn in the Bible, God’s Word, that Jesus is called the “firstborn of all creation,” we learn in verse 16 that everything else in heaven and on earth was created through Jesus. The visible and the invisible. Everything else (everything except Jehovah God and Jesus Christ) was created through Jesus and for Jesus. And in verse 17 we learn that Jesus existed before everything else. This obviously excludes the one who created Jesus Christ, Jehovah God. And that everything else was made through Jesus so that it could exist.
