If the God of the Bible is alive and his word is true, then those who put their faith in God through Christ have God’s word living in them. In the context of the scripture passages cited above, while Jesus- the Word would not be excluded, what is meant is the written word. By the Spirit who gave it, that word is alive and active in the lives of all who have put their faith in Jesus. That suggests a number of things, and ought to open us up more to wanting to hear God’s voice through the pages of scripture.
We in Jesus ought to be people of the Book. We should be regularly reading through all of it, from Genesis to Revelation. One can listen to it nowadays as well, of course. We need the entire Book, even if we don’t understand why in the world we need certain parts of it. It helps us get into a certain rhythm and helps us be open to the Spirit’s voice and work in our lives, in ways in which we often may not understand.
God’s word living in us suggests that God is active in that word in our lives. While certainly the prophetic word given by the Spirit is not excluded (see passages like 1 Corinthians 14), what is primarily meant, I take it, is scripture. And the dynamic is a life lived not just with words memorized or heard, or even brought to mind by the Spirit, though that last point is getting closer to the point here. What is meant is nothing less than the dynamism of God’s word active, alive in us. Working in our own lives to change us. And working out from our lives to point others to God’s word and his revelation to the world in Jesus.
Yes, we have this word in and through Jesus to be lived out together for the world.
