Resurrection, the first
'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.

Face of the ground
In Genesis 8:8, this signifies what people in the church have in them, the word ground being used because this is a person's first stage in becoming a church.Later, the face of the ground being dried up in Genesis 8:13 signifies regeneration when falsities no longer appeared.
