Those who believe that perseverance is required to enter the kingdom are in bondage to a way of thinking that makes assurance impossible prior to death. And not knowing where you are going until after you die is a bad thing, for at that point there won’t be anything you can do about it.
Perseverance is commanded. And rewards are promised to those believers who persevere. The fact that eternal life is guaranteed, whether we persevere or not, in no way lessens the rewards or cheapens the grace of God. We don’t buy our way into the kingdom by perseverance in good works. That is a gift of God’s unmerited favor.
I mostly agree though I might would state it slightly different. This is one of the reasons that I reject Arminianism as well as Calvinism.
I believe there is very little doubt when someone actually extols the value of Jesus Christ to them personally. It shows that the person has a meaningful relationship to God to the point of sharing their personal experiences. I believe this is why John said....
1Jn 4:14 And we have seen and do testify that the Father sent the Son to be the Saviour of the world.
1Jn 4:15 Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God.
1Jn 4:16 And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.
God knows that I sin more than most anyone would accept as being indicative of redemption. (though sins to me as I age are more about attitudes and conditions. Not that still don't make big mistakes. I do.)
I'm glad that no man is Judge of another. I don't call "balls and strikes" relative to a relationship with God. I'm not the One that needs to be pleased.
1Co 4:3 But with me it is a very small thing that I should be judged of you, or of man's judgment: yea, I judge not mine own self.
1Co 4:4 For I know nothing by myself; yet am I not hereby justified: but he that judgeth me is the Lord.
1Co 4:5 Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.
One day, God will speak and all men will stand silent as He declares His judgements.
I do believe that some Arminians approach Salvation with a plan to "win God with their works". They believe repentance in prayer goes like this....
"God, if you forgive me, I will never do that again. God empower me to keep your commandments" (that is my version of some Arminian style prayers that might take place.....)
I have concerns with this view of repentance.
I do believe Paul got it exactly right when dealing with sin in the life of the Redeemed.
2Ti 2:19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
2Ti 2:20 But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour.
2Ti 2:21 If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.
It is interesting to witness the fact that Paul follows the command to "depart from iniquity" with words I believe define realties in this life.
2Ti 2:20 But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour
Purge we must..... but the reality is.... this is a battle we never complete until we are made complete in the Resurrection.
