158. "'Be watchful.'" (3:2) This symbolically means that they should have truths and live in accordance with them.

To be watchful has precisely this symbolic meaning in the Word, for a person who learns truths and lives according to them is like someone who awakens from sleep and becomes alert. By contrast, a person who lacks truths, but who is engaged simply in worship, is like someone who is asleep and dreaming.

Natural life, regarded in itself or apart from spiritual life, is really no more than a state of sleep, whereas natural life that contains spiritual life is a state of alertness. This alertness, moreover, is obtained only through truths - truths which appear in their own light and in their own clarity when a person lives in accordance with them.

This is the symbolic meaning of watching in the following passages:

Watch..., for you do not know at what hour your Lord will come. (Matthew 24:42)

Blessed are those servants whom the Lord, when he comes, will find watching... Be ready, for the Son of Man will come at an hour you do not expect. (Luke 12:37, 40)

Watch..., for you do not know when the lord of the house will come..., lest, when he comes suddenly, he find you sleeping. What I say to you, I say to all: Watch! (Mark 13:35-37)

While the bridegroom was delayed, (the virgins)...slumbered and slept... And the (five foolish) virgins came..., saying, "Lord, Lord, open to us!" But (the Lord) answered..., ."..I do not know you." Watch therefore, for you know neither the day nor the hour at which the Son of Man will come. (Matthew 25:1-13)

Because the Lord's coming is called the morning (no. 151), and truths are then revealed and light dawns, therefore that time is called "the beginning of the watches" in Lamentations 2:19, and the Lord is called "a watcher" in Daniel 4:13. Moreover we read in Isaiah,

Your dead shall live... Awake..., you who dwell in dust. (Isaiah 26:19)

To be shown that the state of a person who lacks truths is called slumbering and sleep, see Jeremiah 51:39, 57, Psalms 13:3; 76:6, Matthew 13:25, and other places.
