Warnings to the churches about gaining eternal death

"… you are that one’s slaves whom you obey, whether (slaves)
of sin leading to (eternal) death, or (slaves) of obedience leading to righteousness
… so now present your members as slaves of righteousness for holiness.
For when you were slaves of sin … the end of those things is (eternal) death.
… For the wages of sin is (eternal) death …" (Romans 6:16-23)

"For those who LIVE according to the flesh set their minds on the things
of the flesh, but those who LIVE according to the Spirit, the things of the Spirit. For to be
carnally-minded is (eternal) death, but to be spiritually-minded is (eternal) life and peace.” (Romans 8:5-6)

"For IF you live according to the flesh you will die (eternal death);
but IF by the Spirit you put to death the deeds of the body, you will live (eternal life).” (Romans 8:13)

“Do not be deceived, God is not mocked; for whatever a man sows,
that he will also reap. For he who sows to his flesh will of the flesh reap corruption
(eternal death), but he who sows to the Spirit will of the Spirit reap everlasting life.” Galatians 6:7-8

“But those who desire to be rich fall into temptation and a snare,
and into may foolish and harmful lusts which drown men in destruction and perdition.
For the love of money is a root of all kinds of evil … Let them (rich Christians) do good,
that they may be rich in good works, ready to give, willing to share, storing up for them-
selves a good foundation for the time to come, that they may lay hold on eternal life.”
(1 Timothy 6:9-19)

“ ‘Now the just shall live by faith; but if anyone draws back,
My soul has no pleasure in him.’ But we are not of those who draw back to perdition,
but of those who believe to the saving of the soul.” (Hebrews 10:36-39)

“Blessed is the man who endures temptation; for when he has been
approved, he will receive the crown of (eternal) life which the Lord has promised to
those who love Him … when desire has conceived, it gives birth to sin; and sin when
it is full-grown, brings forth (eternal) death. Do not be deceived, my beloved brethren.”
(James 1:12-15)
