What is considered sinful in Christianity?

Answer 1

Sin is the disobedience and rejection of God. Humanity inherits sin through the disobedience of the first man who disobeyed a direct command of God. This original sin resulted in a separation from God. As inheritors of this original sin, the only way for the power of sin in us to be broken and a reunion with God is through the saving grace available through a belief in the Lord Jesus Christ- the only mediator and advocate between us and God. Heaven in full communion with God, sin is a full rejection of God. all the laws given (the "thou shalts and thou shalt nots") are a reminder of the consequences of sin and are myriad in numbers. To simplify things, Christ condensed the "laws" into 2 key elements. Love God completely (reunite with God) and Love others as you would love yourself. From this it can be seen that, even though one may obey all of the laws of the land, one can still sin.

Answer 2

Sin is being less than what God wants us to be, and He said to be perfect as our father in heaven is perfect. So any act or omission that tends to lead us away from God and not toward him is a sin.

A mortal sin needs to have three characteristics. It needs to be grave matter, there has to be full understanding that it is grave matter, and there must be full consent of the will.
