The Lord is life itself, and we are recipients of life. This is true even of the most evil spirits, who loved only themselves in life and hate and deny the Lord from their place in the lowest hells; the Lord forces life upon them, despite their rejection, in the amount necessary to keep them from ceasing to exist. The situation is much different, of course, with people who accept and follow the Lord; by doing this they open themselves up to the inflow of life, and become more full the more open they are. This is the “life” in question when the Bible uses that word. It indicates spiritual life, the life that comes from the Lord into our hearts and minds. We accept life from the Lord by learning about Him, learning what is right and wrong, and by determining that we will stop doing what's wrong and instead do what is right.

'The third day' as in Genesis 22:4, signifies something complete and a beginning of sanctification. 'Day,' in the Word, signifies a state, as do all references to time. When 'third' is added, it signifies the end of that state and the beginning of the following state. In the internal sense of the Word, 'three days' and 'the third day' signify the same thing. The Lord rose again on the third day, which is also why the Lord distinguished the stages of his life into three in Luke 8:32. The Lord also endured the last temptation on the cross, on 'the third hour of the day' in Mark 15:25. In Exodus 19:16, 'the third day' signifies the end of a state of preparation for reception, and so an end of purification. In Hosea 6:2, 8, 'the third day' has the same meaning as 'the seventh day,' which is a state of peace.
