The further refutation of unconditional eternal security, is found in scripture such as
Hebrews 6,:4-8 which is unequivocally talking about those who were born again, because they were made partakers of the Holy Spirit - which only happens at salvation - yet they fell completely away from the faith into total apostasy (fell away - parapipto- apostatized), and since they lost their faith completely, they can’t be renewed again into repentance, (any more than you could get an atheist to repent), and their unbelief in effect is crucifying Jesus again, since unbelief is why they crucified Jesus in the first place.
This falls right in line with the warning from
Hebrews 3:12-15 to the brethren about guarding against acquiring an evil heart of unbelief, due to deception that comes from sin, and then departing from the living God.
Living sinfully eventually hardens the heart into unbelief, and when faith is fallen away from, a believer departs from the living God.
And
Hebrews 6 falls in line with Jesus teaching us that some believe, but only for awhile, and then fall away. in
Luke 8:
In
Luke 8. Jesus tells the parable of the sower who sows the seed of the word of God.
Some seed sown lands on a rock. The seed GROWS, and thus results in new life, but then it withers and dies.
Jesus in the example of the seed sown on a rock, shows that some people BELIEVE for a while, but then FALL AWAY.
Luk 8:5 A sower went out to sow his seed...
Luk 8:6 And some fell upon a rock; and as soon as it was sprung up, it withered away, because it lacked moisture.
Luk 8:13
They on the rock are they, which, when they hear, *receive the word with joy*; and these have no root, which FOR A WHILE BELIEVE, and in time of temptation FALL AWAY.
Notice above, they *received the word with joy*
To receive the word with joy, is to become a follower of Jesus Christ:
1Th 1:6 And ye became followers of us, and of the Lord, having
received the word in much affliction,
with joy of the Holy Ghost.
Some believe for a while, then fall away said Jesus - OSAS is thus falsified.
The brethren can harden their heart by sinning and depart from God- OSAS is falsified.
James 5:19 My
brothers, if anyone among
you wanders from the truth and someone brings him back,
Jas 5:20 let him know that
whoever brings back a sinner from his wandering will
save his soul from death and will cover a multitude of sins.
