Acrid bitterness inevitably seeps into the lives of people who harbor grudges and suppress anger, and bitterness is always a poison. It keeps your pain alive instead of letting you deal with it and get beyond it. Bitterness sentences you to relive the hurt over and over.
Lee StrobelI think there's a faith formula in that verse: believe plus receive equals become. So I think believing's important, having intellectual agreement with Christian doctrine is important, but there has to be a time when we receive God's gift of grace - not that we've earned it or merit it or deserve it - but receive this free gift of forgiveness and eternal life that Jesus purchased on the cross for us.
