Jehovah
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.
Feet
Our feet are the lowest parts of our bodies, and they're very useful! In the Bible, feet represent the lowest and most utilitarian part of our spiritual selves -- the “natural” level. This everyday aspect of life is involved with routine tasks and demands and the thoughts associated with them. It's not terribly deep or introspective, but it is useful -- just like feet. This correspondence is true of the Lord and of church communities, too. The Lord's Divine Natural leads us through relatively simple obedience (think of the Ten Commandments). Churches, too, have a natural level on which they serve their communities in simple but tangible ways.
