>>In regards to the beliefs I was referring to: I believe I am asking forgiveness for all sins I have committed to retain my salvation....”
Or “I believe I have accepted Jesus Christ as my Lord and Saviour.”
There’s no real difference here. You ‘believe’ you’ve done what you need to achieve your salvation. You’re choosing to believe can be as much as work as anything else.
And you could be as wrong; what you believe now may not be what you believe later. You do not know and cannot presume to know the future. Only God can.
You chose Christ and you can choose not Christ in the future:
“For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.” - 2 Peter 2:20-21
When you accept Christ as your Savior, it isn’t an “I believe” moment.
You know. There is no doubt. You will always remember the moment, for ever. It is an unwavering knowledge. If you don’t know this, if you are unsure, then you haven’t accepted Christ as your Savior.
Even if you think, in your worldly selfishness that you can then reject Him, you will still remember when you accepted Him.
