OSAS is really a derogatory term used by those who do not trust that JESUS will keep them saved.
Those opposed believe that a regenerate, born again, Child of God, who has a NEW heart, and is a NEW Creation IN CHRIST, can do something to be unborn again. God is NOT going to cast ANY of HIS human, born again Children into Hell.
The strange thing about this belief idea is the opposite of discipleship along with a conviction that a sinful
lost heart is not a problem, and just belonging to a belief group is knowing God.
If Paul believed knowing God was obvious and our hearts do not easily deceive ourselves he would not
have said this
1 This will be my third visit to you. "
Every matter must be established by the testimony of two or three witnesses."
2 I already
gave you a warning when I was with you the second time. I now repeat it while absent: On my return I will not spare those who sinned earlier or any of the others,
3 since
you are demanding proof that Christ is speaking through me. He is not weak in dealing with you, but is powerful among you.
4 For to be sure, he was crucified in weakness, yet he lives by God's power. Likewise, we are weak in him, yet by God's power we will live with him to serve you.
5
Examine yourselves to see whether you are in the faith;
test yourselves. Do you not realise that
Christ Jesus is in you--
unless, of course, you fail the test?
6 And
I trust that you will discover that we have not failed the test.
2 Cor 13:1-6
Paul is facing believers who are claiming Paul is not speaking Gods word.
He is then challenging those who are accusing him to test themselves that
they actually know Jesus.
This is exactly the same as my experience. Quoting simple spiritual realities are
questioned and thrown out by people who claim to know Christ yet do not have
cleansed hearts or a desire to walk righteously.
Put simply this shows they do not know Jesus, or His gospel yet claim aggressively
they speak authoritatively yet speak directly against Jesus and His word.
It therefore suggests simply coming to faith and knowing God is not as automatic
and simple as many are claiming. In reality making sure of your faith is part of our walk.
10 Therefore, my brothers, be all the more eager to
make your calling and election sure.
For
if you do these things, you will never fall
2 Peter 1:10
