Christians, what is the definition of sin in your bible?

Sin by definition of the bible is the transgression to the will of God. Jesus clearly says there are only two law not ten - Love God above all and Love thy neighbor - this definitions encomp the whole bible and the law.Breaking any of the two rules is sin , however God made man the power of discernment but Satan gets into the way to trick everyone to love oneself and leave the rest.This is the cause of humanity problem being planted by Satan to all people who does not know how to hold on the very two rules.
