Not so, a person is dead in their sins and trespasses until they die in Christ, upon which they are made alive, given the fire of the spirit. Have you not experienced it? You must be born again.
Nobody who hasn't been born again, ie baptised with fire and the spirit can enter the Kingdom. That's because it takes exomolgeo, giving it up for God, casting to the wind what you think you know, who you think you are, all those false idols we've all been indoctrinated with. Once that occurs, the hand is set to the plow.
God's Kingdom is radically different, there's no friendship between the world and the table of demons. A believer can't love God and love Nasa, for instance, the two are irreconcilable.
When God says He's going to bless and save all the nations, when He sends Jesus to be the saviour of the world, when He seals His promise in holy blood, and when He gives us end-time visions of deliverance of the nations in the renewal of all things, I believe Him. Now, it may be that many find that great truth offensive (a stumbling stone to Jews and foolishness to Greeks), but so be it, God has no fellowship with the fallen ways of the world, He's intent on restoring creation to His image. He doesn't love you or me any less than He loves the hookers and tax collectors downtown.
All things are in His hands, and for Him to change the heart of a fornicator, an idolater, an adulterer, an effeminate, an abuser of themselves with men, a thief, the covetous, a drunkard, a reviler, or an extortioner is a beautiful thing. Miracles are commonplace in the Kingdom, and what's impossible for man is certainly not impossible for God.
So there's no 'time limits' on 'your salvation'. It's nothing you do, how can you talk about it like it's some sort of achievement on your part, that's self-righteousness - you have your reward. God appoints the time for salvation of all men, it's all in His hands. All things from Him, through Him and to Him. Exitus et reditus. Perhaps you should submit to Christ.
