Sealed or not is depend oN what we do.
If we do like this
Galatians 5:21
“Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.”
Than No heaven or No sealed
Ok Mr Galations 5:21 . As I've said we have two options with your one verse . Either " inheritance ' refers to ' rewards or it refers to unbelievers. Many places unbelievers are referenced to as to sinners ( we are all sinners ) certain sins ( ungodly , unrighteous, clouds without water ,wicked , whores , dogs , sons of perdition , )
or they are described like this in Romans 1 and 3
13Their throat
is an open sepulchre; with their tongues they have used deceit; the poison of asps
is under their lips:
14Whose mouth
is full of cursing and bitterness:
15Their feet
are swift to shed blood:
16Destruction and misery
are in their ways:
17And the way of peace have they not known:
18There is no fear of God before their eyes.
27And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
28¶And even as they did not like to retain God in
their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
Rom 1
29Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
This how the bible describes those who are not saved . Its a contrast. Not that believers don't sin .
So your one verse has to line up with the many verses I keep saying about being sealed and guaranteed.
