The Prophetical Books:

1. Internal Meaning of Isaiah, Chapter 1 (1)

1-8 The church has been vastated by evil of life, (3)

9 so that there is little of a residue. (3)

10-15 Therefore their external worship is of no avail. (3)

16-19 Exhortation that they should repent of the evil of life, and thus they will receive good. (3)

20-23They falsify the Word. (3)

24-27 The Lord when He comes will destroy them, and will establish the church with others; (1, 11)

28-31 This when nothing of the church remains with them. (3)

'Washing of the hands' was an ancient declaration of innocence, and signifies purification from evils and falsities, as in Psalms 73:13 and Matthew 27:24.

202. Baptism

Baptism was instituted as a sign that an individual belongs to the church and as a reminder that she or he needs to be regenerated. The washing of baptism is actually the spiritual washing that is regeneration.
