It’s easy to apologize to God for past sins or evil actions; and promise not to take part in these actions. Even promising not to be angry with others is often a goal that many of us have, but is often a difficult feat when inconveniences occur. In the Osashizu, God tells us that he does not want apologies or repentance for past sins, but he does want us to do one thing. The following is from the divine directions given on February 18, 1892:

You have already been through various situations. Repentance for the past need hardly be discussed. Repentance upon seeing something. Repentance when shown something. I am talking about things that lie ahead. Repentance is to resolve all situations that lie ahead for the rest of your life. You must make this resolve, first and foremost. Listen and understand well. I am not talking about repentance for the past. What you need to do is to resolve all situations that lie ahead. 

God accepts our apologies when we calm our minds, and do not act upon the evil thoughts that may exist in our minds when inconveniences and temptations occur in the future. This is often very difficult to do, but God promises that if we purify our minds, there will be a path of joy.
