Salvation is provided for you by God, and guaranteed to remain available to you by God, but your personal salvation is not in God’s hands- it is in your hands.
God has provided Messiah, and Messiah provided the means for us to be forgiven without the Temple ( the sin and guilt sacrifices had to be slaughtered in the courtyard of the Temple, so after it was destroyed there was no longer any place for us to sacrifice and be forgiven), so the only thing left with regard to our salvation is now in our hands.
We must be the ones to ask for it; we must do T’shuvah (repentance, literally “to turn” from sin), and we must maintain that attitude and demonstrate our true repentance by producing good fruits, which starts with observance and obedience to God’s will and commandments found in Torah and subsequent scripture.
Too many people are taught that “once saved, always saved”, which implies that once you ask for forgiveness through Yeshua’s sacrifice, then you have it always. No matter what you do or say or how you act, once saved…well, that ain’t the way it happens, Folks! Once saved, always saved AS LONG AS you continue to repent of your sins (which we will always do, no matter how hard we try not to) and AS LONG AS you continue to study the word, edify each other, love more than you did before and show everyone that God has changed you through the Ruach HaKodesh (Holy Spirit) by your actions and words.
We must show that we are able to love more, forgive readily, glorify God, obey His word (all of it, from Genesis through Revelation), maintain an attitude of humility and servitude to God, constantly ask forgiveness in Yeshua’s name, and pray for the strength and guidance of the Holy Spirit to help us sin less.
Not every one of us is going to be able to do every thing on that list, or all of it all at the same time, consistently, but these are the things we need to do. That’s a lot of things to do, and none of them are easy. It’s all up to you to demonstrate your obedience (to Torah), which includes your repentance (of your sins), through which you gain your justification (by Yeshua’s sacrifice), which provides your salvation (the Grace of God.)
The more you obey, the more blessings you get; the more you “die to self”, the more you can be filled with the Ruach haKodesh; the more you work at it, the more you will get from it.
Sounds a lot like life, doesn’t it? And why not? Salvation IS life, and our life on earth is designed for one purpose- we spend time here to choose where we spend eternity.
And that, again, is totally up to you to decide for yourself.
