Much like the Arminianism/Open Theism you seem to espouse. BTW, you have no right to claim you will presevere either. If salvation is yours to provide for yourself, it's yours to repudiate.
And Reformed folks believe in Preservation of the saints. God does the preserving. Typical of man-centered theology, you phrase it as perseverance, as if it depends on you. The reformed say it's of God.
What is there to persevere? Jesus said he that believes on him is passed from death to life and shall not come into condemnation.
John 5:24 Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is
passed from death unto life.
The Bible says we are sealed by the Holy Spirit when we believe.
Eph 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
This seal is permanent. What was the seal given Abraham when he believed and God imputed righteousness to him? Circumcision.
Rom 4:11 And he received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised: that he might be the father of all them that believe, though they be not circumcised; that righteousness might be imputed unto them also:
Can circumcision be undone?
So, I am not persevering, I am not enduring, I am resting safe.
So, as you can see, I am not Arminian as some of you falsely charge.
