It is what the modern "church" has taught you.
It is lies. It was even prophesied...
O YHVH, my strength and my stronghold, my refuge in the day of trouble, to you shall the nations come from the ends of the earth and say: "Our fathers have inherited nothing but lies, worthless things in which there is no profit.
Jeremiah 16:19 (ESV2011, MBM)
The teaching you do is against the Messiah Himself. (wake up please)
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.
Matthew 5:19 (KJV, MBM)
Admit it. We were tricked.
Of course justification only comes through faith in Messiah. Everyone knows this.
But to teach people NOT to obey God's commandments is a trick straight from hell.
Don't be tricked.
Wake up.
