Jesus experienced life with human emotions.
In addition to knowing our need for salvation, Jesus fully experienced everything that we need to be saved from.
From Winn Collier.
Jesus did not come to help us manoeuvre around the our brokenness; Jesus came to enter our brokenness with us. The gospel is not a therapeutic system tooled for enhancing our ability to cope by believing hard enough and smiling big enough and quoting just the right mixture of Bible verses so we can distance ourselves from our negative emotions. The gospel is the story of the world as it actually is, our lives as they actually are. The gospel tells us that we are broken, more broken that we know, and that our world is in a shambles. Jesus does not encourage us to ignore what we have lost, but rather to mourn it, to feel deep sorrow over the devastation we were never supposed to know. The gospel instructs us to want and wait and hope for God to make the world right again. We do not need a God removed from our destruction and insisting we are all okay. We need a God who knows in his bones how sick we are and who will not leave us to ourselves. We need God to rescue us.
