Well, there are times when I feel completely drained and then I will pray and feel refreshed. God said to (Paul), "My grace is sufficient enough for thee." In my weakness, God's strength is made perfect.
Then there are times when I may be crying or feeling weary but then I will just think of God and start saying Hallelujah or praying. And then The Holy Spirit makes me laugh and smile in the midst of me having just cried. It's actually a weird phenomenon that in the middle of tragedy I still can laugh and smile and feel happy. I'm amazed myself sometimes and say, "So, this is what it means to have peace that passeth all understanding."
