Nope! The Bible says that we can know that we are saved now. I am saved now. I am not perfect. But God saved me.
I knew it when God called me. I know it when he has to chastise me. I know it when I feel the Holy Spirit guiding me. I know it when Christ shepherds me.
If you think I am just basing my faith on my interpretation or someone else's interpretation, I can't help you at all on that.
Every appeal to scripture is an appeal to someone’s interpretation of scripture. It’s at the point of interpretation that things go wrong.
OSAS is not taught by scripture, this is a new human founded interpretation of Scripture.
If I had to live my life every day not knowing if I were going to be with Christ or burn in hell, I would go mad.
Salvation is a process not a fait accompli. God is faithful for His part, but we must endure to the end.
We must remain in His Love.
Philippians 3:11-14 If by any means I might attain unto the resurrection of the dead. [12] Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus. [13] Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, [14] I press toward the mark for the prize of the high calling of God in Christ Jesus.”
Paul didn’t treat salvation as already attained.
Romans 13:11 “And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed.”
1 Peter 2:2 (RSV) “Like newborn babes, long for the pure spiritual milk, that by it you may grow up to salvation;”
Colossians 1:21-23 “And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled [22] In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight: [23] If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard.”
Hebrews 3:14 “For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;”
Revelation 3:10-12 “Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth. [11] Behold, I come quickly: hold that fast which thou hast, that no man take thy crown. [12] Him that overcometh will I make a pillar in the temple of my God,”
Revelation 2:10 “Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life.”
OSAS is actually one of the most dangerous doctrines to hold to, as comforting as people think it is, it is not the right understanding of salvation.
