1 John 3:4

Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.

Repentance means changing your mind about sin. If you keep sinning as if there's no issue with it, you have no truth in you. If your conscience causes you to feel guilty when you commit a sin, you are on the right path.

Proverbs 7:2

Keep my commandments, and live; and my law as the apple of thine eye.

All of us have sinned. Some of us have changed our minds about sin and turned to Christ. Does that mean we keep doing our own thing and live our lives in sin?

Romans 3:31

Do we then make void the law through faith? God forbid: yea, we establish the law.

There are 10 commandments, and they can be summed up in 2 commandments. Love God with all your heart, mind, and soul (the first 4) and love your neighbor as yourself (the last 6).

Matthew 22:37-40

37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.

38 This is the first and great commandment.

39 And the second is like unto it, Thou shalt love thy neighbour as thyself.

40 On these two commandments hang all the law and the prophets.
