Q. 24. What is sin?
A. Sin is any want of conformity unto, or transgression of, any law of God, given as a rule to the reasonable creature.[92]

[92] 1 John 3:4. Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. Galatians 3:10, 12. For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.... And the law is not of faith: but, The man that doeth them shall live in them.
