But yes his sacrifice is sufficient to cover all sin for all time , he just doesn’t force people to accept his covenant word and blood he gives us the choice by sending the gospel out among us all
“And he said unto them, Go ye into all the world, and preach the gospel to every creature.( because it can save them all )
He that believeth and is baptized shall be saved;
but he that believeth not shall be damned.”
Mark 16:15-16 KJV
he died for us all and he spoke to us all

If you interpret the salvation (deliverance) right, belief, baptism, accepting, confessing, repenting, following God's commandments, etc, are not the cause of eternal inheritance.
All of these efforts of, born again, children of God, are necessary to follow God's instructions as to live an abundant, and joyful life here on earth, as we fellowship with one another, and with God.
"being damned" is being judged worthy of punishment, which brings about God's chastenings, but it does not cause a child of God to lose their eternal inheritance.
Understanding the gospel, also, does not cause our eternal inheritance, but it does cause his children, if they follow his instructions in the gospel, to enjoy that good and joyful life as they sojourn here on earth.
The inspired words of God are not written to the natural man, instructing him how to get delivered eternally. The natural man cannot discern the inspired spiritual words of God. They are written to God's born again children, instructing them how to live their lives as they sojourn here on earth, also telling them how that they already have the promise of their eternal inheritance.
