1 John 2:1
My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.
We have such an awesome hope in Jesus because no matter what we do if we return to him He will take us back and love us like we never left. Just as we fight for others; elderly, unborn, disabled, etc...
When we let God fight for us we are essentially giving our problems to him and letting him take complete care of us. That is really all God asks of us. He wants to be our Advocate and trust in him to take care of us.
Who do you advocate for? How do you fight for others?
We all fight for something, make it worth while :)
