The Lord, in the simplest terms, is love itself expressed as wisdom itself. In philosophic terms, love is the Lord's substance and wisdom is His form. Of course, we feel the Lord's love and hear His wisdom in many different ways, depending on our state in life and how receptive we are. That's why the Lord has so many different names in the Bible, and is referred to in so many different ways.

359. We could not be images of God according to his likeness unless he were within us and were our life from our very center. God's presence within us and God's being our life from our very center follow from what I explained in 4-6 above, namely that God alone is life and that we and angels are life-receivers from him.

The Word tells us that God is in us and makes his home with us; and because the Word tells us this, preachers are fond of telling us to prepare ourselves to let God come into our lives so that he may be in our hearts and that our hearts may be his dwelling. The devout say the same in their prayers. Some [preachers] talk and preach more explicitly about the Holy Spirit, who they believe is within them when they are filled with holy zeal as the source of their thought, speech, and preaching. I have explained in 51-53 of Teachings for the New Jerusalem on the Lord that the Holy Spirit is the Lord and not some God who is a separate individual. The Lord actually says, "In that day you will know that you are in me and I in you" (John 14:21 [20]), and he says similar things in John 15:24 [4] and John 17:23.
