John 10:27-30 disagrees with you. To be saved means to assent to His Lordship. You are no longer your own. Hew bought you out of the market with His Blood, and not even you yourself can escape His ownership. And He never lets go. If you do not understand this, know this, and agree with it, you are not saved. Romans 3:22-26.
The two hands of God hold His believers. JESUS said so!
I have seen too many scriptures warning about turning away from Jesus (I.e Hebrews) and too many Christians fall away from the faith in my 25 years of walking with Him hold the false doctrine of “once saved always saved”. I suggest you do like Paul warned you in Phillipians and Work out your salvation with fear and trembling. Guess I’m not saved for quoting scripture, huh?
