As believers in the Lord we have the Spirit of God within and the Word of God without, and everything that we experience of the Lord is related to these two. If we neglect the Word of God outside of us and we don’t read it regularly, no matter how much we seek the Spirit within, our experience is not that rich and not that meanigful. Everything needs to be based on the Word of God – and the way we read and get into the Word is by praying over the Word to enjoy the Spirit in the Word. When we exercise our spirit to read the Word and pray over the Word, the written Word becomes the rhema, the living Word to nourish us and supply us!
we need to be constituted with the truth
This is not just an expression – being constituted with the truth – and it not just something we desire to do, but this is our need! If we love the Lord, we also need to love His Word and keep His Word (John 14:15), that is, get into His Word! We need to do our best to get ourselves into the divine truths revealed in the Word of God and get the truth constituted into our being.
