William Secker says - (2nd Birth/2nd Death)

"If the second birth have no place in you, the second death will assuredly have power over you."
The Nonsuch Professor p.119

Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.

John 3:3

Then death and the grave were thrown into the lake of fire. This lake of fire is the second death.

Revelation 20:14 NLT
