What Christianity Means

God created us and He wants us to do good. We are not able to do good on our own. God because of His law must punish us but He has come up with a way so that we can be credited with good works so that we will be able to live with Him forever.

He decided to make His son live perfectly, and then sacrificed Him for all of our sins

Now we do not have to be perfect just accept the sacrifice of Jesus to cover our mistakes 

God wants us to live good lives but we cannot do it perfectly on our own
