When the Bible speaks of "Jehovah," it is representing love itself, the inmost love that is the essence of the Lord. That divine love is one, whole and complete in itself, and Jehovah also is one, a name applied only to the Lord. The divine love expresses itself in the form of wisdom. Love, then, is the essence of God -- His inmost. Wisdom -- the loving understanding of how to put love into action -- is slightly more external, giving love a way to express itself. Wisdom, however, is expressed in a great variety of thoughts and ideas, what the Writings collectively call divine truth. There are also many imaginary gods, and sometimes angels and people can be called gods (the Lord said Moses would be as a god to Aaron). So when the Bible calls the Lord "God," it is in most cases referring to divine truth. In other cases, "God" has reference to what is called the divine human. The case there is this: As human beings, we cannot engage the Lord directly as divine love. It is too powerful and too pure. Instead, we have to approach Him by understanding Him through divine truth. Divine truth, then, is the Lord in human form, a form we can approach and understand. Thus "God" is also used in reference to this human aspect, because it is an expression of truth.

2811. 'And Abraham built the altar there' means preparation of the Lord's Divine human. This is clear from the meaning of 'the altar' and of 'building the altar'. Altars used to mean all worship in general because they were the chief feature of the worship of the representative Church, 921. And because they meant all worship in general they meant the Lord's Divine Human, for the Lord's Divine Human is essentially present in all worship and all doctrine, so much so that it is the very essence of worship itself and doctrine itself. This becomes clear also from the Holy Supper which superseded altars, that is, burnt offerings and sacrifices, 2165, 2187, 2343, 2359. The Holy Supper is the chief feature of external worship because it is the Lord's Divine Human that is bestowed there. From all this it may become clear, and so without further explanation, that 'building an altar' means preparing the Divine human. The final preparation of the Lord's Divine human for undergoing the last degrees of temptation is the subject in the present verse and is described by the statement that Abraham laid the pieces of wood in order, bound Isaac his son, and laid him on the altar, upon the pieces of wood.
