According to Paul, if someone breaks the sabbath law they are guilty of breaking them all. So a sabbath breaker is as bad as a murderer. So sure, SDA will be judged as they judge others too. Satan is the accuser of the brethren.
Accordint to Paul, accordint to Paul , Paul this, Paul that! What about what Jesus the son of God and God himself have to say? it is very limiting to Follow only Paul and ignore the rest of scripture here is Why;
No. Not all sins are equal in the eyes of God according to Scripture. Jesus Himself made this clear explicitly and repeatedly.
Jesus Said So Directly
When Pilate told Jesus that he had the power to crucify Him or release Him Jesus responded with something that directly addresses your question:
Jesus answered you could have no power at all against Me unless it had been given you from above. Therefore the one who delivered Me to you has the greater sin. (John 19:11 NKJV)
The greater sin. Jesus used a comparative. Greater than what? Greater than Pilate's sin of cowardice and weakness in condemning an innocent man. Both Pilate and Judas sinned. But Jesus said one sin was greater than the other.
That single statement from Jesus demolishes the idea that all sins are equal before God.
He also said this about those who would cause children to stumble:
But whoever causes one of these little ones who believe in Me to sin it would be better for him if a millstone were hung around his neck and he were drowned in the depth of the sea. (Matthew 18:6 NKJV)
Better for him if he were drowned. That is the language of a sin that carries a heavier weight and a heavier consequence than ordinary sin. Jesus was not describing all sin as equal here. He was describing a category of sin that provokes an especially severe response from God.
And in the Sermon on the Mount Jesus described degrees within sin itself. He took the commandment against murder and went deeper into the heart behind it showing that anger, contempt and verbal abuse each carry their own specific consequences:
But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment. And whoever says to his brother Raca shall be in danger of the council. But whoever says you fool shall be in danger of hell fire.(Matthew 5:22 NKJV)
Three levels. Three different consequences. Danger of judgment. Danger of the council. Danger of hell fire. If all sins were equal Jesus would not have made these distinctions. He was showing that sin exists in degrees of seriousness and carries corresponding degrees of consequence.
He also said something that directly addresses the question of teachers and leaders who lead others astray:
Whosoever therefore shall break one of these least commandments and shall teach men so shall be called least in the kingdom of heaven but whosoever shall do and teach them the same shall be called great in the kingdom of heaven.(Matthew 5:19 NKJV)
Least and great. Degrees of standing in the kingdom based on obedience and teaching. Not all violations are treated equally.
The Old Testament Confirms It
The Law of Moses itself made a clear distinction between sins committed deliberately and sins committed unintentionally. Unintentional sins had specific sacrificial remedies provided. But deliberate presumptuous sins, sins committed with a high hand as the Hebrew puts it, carried a far more severe consequence:
But the person who does anything presumptuously whether he is native born or a stranger that one brings reproach on the Lord and he shall be cut off from among his people. (Numbers 15:30 NKJV)
Cut off. No sacrificial remedy provided. The presumptuous deliberate sin was in a different category entirely from the unintentional sin. God Himself made that distinction in His own law.
And Solomon confirmed that God weighs sins differently when he wrote:
These six things the Lord hates yes seven are an abomination to Him. (Proverbs 6:16 NKJV)
God hates certain things more than others. He calls specific sins an abomination. That is the language of degrees not equality.
The One Unforgivable Sin
And then there is the sin that Jesus described as unforgivable which places it in a category entirely above every other sin:
Therefore I say to you every sin and blasphemy will be forgiven men but the blasphemy against the Spirit will not be forgiven men. (Matthew 12:31 NKJV)
Every sin and blasphemy will be forgiven. But not this one. If all sins were equal before God then either all sins would be forgivable or none would be. The fact that one specific sin stands alone as unforgivable while every other sin can be forgiven through genuine repentance and faith demonstrates beyond any argument that sins are not equal in God's eyes.
What Is Equal
Now here is the important nuance that keeps this honest and balanced. While sins are not all equal in their nature, their degree of seriousness and their consequences, they are equal in one specific sense. Any sin, however small it may seem, separates a person from a holy God and requires the blood of Christ for forgiveness. There is no sin so minor that a person can stand before God in their own righteousness because of it. Every sin without exception requires the grace of God.
But that truth does not make all sins equal in weight, in consequence or in the degree of accountability they carry before God. Jesus was absolutely clear about that. And the most sobering implication of what He taught is this. The person who knows the truth and teaches others to disregard it bears a greater sin than the person who simply does not know. Which makes the responsibility of every teacher and every believer who handles the word of God all the more serious and all the more urgent.
For everyone to whom much is given from him much will be required. (Luke 12:48 NKJV)
