Yes, to satisfy his justice, God himself, out of mere mercy, reconciles us to himself and delivers us from sin and from the punishment for sin, by a Redeemer.
No, every sin is against the sovereignty, holiness, and goodness of God, and against his righteous law, and God is righteously angry with our sins and will punish them in his just judgment both in this life, and in the life to come.
Idolatry is trusting in created things rather than the Creator for our hope and happiness, significance and security.
Sin is rejecting or ignoring God in the world he created, rebelling against him by living without reference to him, not being or doing what he requires in his law—resulting in our death and the disintegration of all creation.
That we may know the holy nature and will of God, and the sinful nature and disobedience of our hearts; and thus our need of a Savior. The law also teaches and exhorts us to live a life worthy of our Savior
No, but because of the disobedience of our first parents, Adam and Eve, all of creation is fallen; we are all born in sin and guilt, corrupt in our nature and unable to keep God’s law.
Since the fall, no mere human has been able to keep the law of God perfectly, but consistently breaks it in thought, word, and deed.
Ninth, that we do not lie or deceive, but speak the truth in love. Tenth, that we are content, not envying anyone or resenting what God has given them or us.
Sixth, that we do not hurt, or hate, or be hostile to our neighbor, but be patient and peaceful, pursuing even our enemies with love. Seventh, that we abstain from sexual immorality and live purely and faithfully, whether in marriage or in single life, avoiding all impure actions, looks, words, thoughts, or desires, and whatever might lead to them. Eighth, that we do not take without permission that which belongs to someone else, nor withhold any good from someone we might benefit.
