Does God want us to always be happy? If so, why does He allow all the pain, negative circumstances, and trials in life? I have been asked this many times. I myself have wrestled with the notion.
John Piper does a masterful job of addressing this age old question.
What, then, shall we say in response to this? If God is for us, who can be against us? He who did not spare his own Son, but gave him up for us all—how will he not also, along with him, graciously give us all things? Romans 8:31-31
I am thankful for a God like this.
