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.

Way, the truth, and the life
In John 14:6, 'the way' is doctrine, 'the truth' is every thing pertaining to doctrine, and 'the life' is the essential good which is the life of truth.
