'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

2834. 'And offered it as a burnt offering instead of his son' means their sanctification and adoption. This is clear from the meaning of 'offering as a burnt offering' as being sanctified, dealt with in 2776, and from the meaning of 'instead of his son' as being adopted, that is to say, by the Lord's Divine Human, meant here by 'Abraham', 2833. The adoption of those who were spiritual is described in John,

Jesus said, I am the vine, you are the branches. He who abides in Me, and I in him, he it is that bears much fruit, for without Me you can do nothing. John 15:5.

'The vine' is the spiritual Church, see 1069.
