I sat there, sobbing and rocking back and forth. God had kept me awake for one purpose: to know that He was there for me. To know that He didn't want me to try to earn my own salvation anymore.
I guess that was when it really struck me: God doesn't want us to bear guilt on our shoulders! God doesn't want us to make ourselves feel miserable! God doesn't want us to wallow in self-condemnation! He wants us to be free! He wants us to feel His forgiveness! He wants us to know that we don't have to earn our own salvation - that He will give it to us if we only ask for it!
At true peace for the first time in ages, I went back to bed. And I fell asleep right away.
