Luke 20:34 And Jesus said to them, “The sons of this age marry and are given in marriage, 35 but those who are considered worthy to attain to that age and to the resurrection from the dead neither marry nor are given in marriage, 36 for they cannot die anymore, because they are equal to angels and are sons of God, being sons of the resurrection.
As it relates to salvation, I never feel "worthy." But those who will be sons and daughters of the resurrection are considered worthy. I believe they are considered worthy because Christ's blood covers them.
Thank you Lord for your precious Son.
