Arcana Coelestia #3205
3205. 'Who is that man there walking in the field to meet us?' means regarding the Rational immersed in good alone, that is to say, an investigation regarding it. This is clear from what has been stated above about Isaac's coming out to meditate in the field, by which is meant a state of the Rational immersed in good, see 3196. Here the rational is meant by 'that man', and being immersed in good by 'walking' - that is to say, by meditating - 'in the field'. 'To meet us' means so as to be joined together.
Turn
If we turn ourselves toward the Lord, we can get the full inflowing of His wisdom and love; if we turn away from Him we cast ourselves into cold and shadow -- we turn ourselves toward hell. In the Bible, "turning" generally refers to a change in spiritual state, as people turn themselves toward the Lord or away from the Lord.
