I John 2:1 NKJV

My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous.

I used to think that it was okay to Sin because I have an advocate with the Father. And as long as I confess even if it is insincere God would forgive me. So I continue to lead a sinful life. But after I have been found was God brought me back to him again, I truly understand the reason why Jesus Christ must be our advocate. God does not want us to sin. He hates it when we sin. And he gets very upset every time we sin. Because he loves us so much he does not want us to face the torment of hell. So he gave his one and only Son for us. As the song goes 有一位神,高坐在荣耀的宝座,却死在十架挽救人堕落。 God does not want me to sin. So I shouldn't use Jesus my advocate as an excuse to sin. If u love a person. You would not want to do anything that make the person you love upset. So if I truly believe in Christ and love God. I should do my best not to sin. :)
