You really need to check your scriptures.
Are you saying now that if you sin you are going to Heaven?
“Least in the Kingdom of Heaven” is not referring to those that will be in the Kingdom but those not in the Kingdom and those that are in the Kingdom referring to them as the least. Let's quickly look at the scriptures....
Matthew 5:19
Whosoever therefore shall break one of these least commandments, and shall
teach men so, he
shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven
Who is the scripture referring to?
Those that
break God's Law and
teach others to do the same.
What will happen to those that are found in unrepentant sin when Jesus returns?
Hebrews 10:26-27
26, For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, 27, But a certain
fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
1 Corinthians 6:9-10
9,
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, 10, nor thieves, nor covetous, nor drunkards, nor revellers, nor extortioners,
shall inherit the kingdom of God.
Galatians 5:19-21
19, Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, 20, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, 21, Envying’s, murders, drunkenness, revelling’s, 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.
Now it is clear in
Matthew 15:19 that we are talking about someone that is
breaking one of God’s commandments and teaching others to do so. They are called
least in the Kingdom of Heaven by those that are in the Kingdom of Heaven because they are not going there. The supporting scriptures provided above (there are others also elsewhere) tell us what happens to those that break God’s commandments that
they shall not inherit the Kingdom of Heaven. This is compared to
Matthew 5:19 which is talking about those breaking God’s commandments and are being referred to as also being the least in God’s Kingdom because they are teaching others to depart from the Kingdom of Heaven.
This also includes the 7th Day Sabbath.
Hope this helps. I have to go out for now have a nice day.
