Why would God allow someone to be so overcome that they can barely stand? Daniel’s collapse wasn't a punishment, but a necessary preparation for receiving divine truth.
The intensity of Daniel's experience, leaving him 'alone' and utterly without strength, served a crucial purpose: it stripped away his natural pride and self-sufficiency. This process of being 'broken down' was essential for him to become a receptive vessel for the profound truths that were about to be revealed.
As Calvin suggests, this dramatic physical reaction is meant to subdue our 'carnal feelings' and 'inborn perverseness.' Only when our natural resistance is overcome and our 'pride and loftiness' are prostrate before God can we truly receive His Word. Daniel’s experience teaches that a humble, emptied state is often a prerequisite for divine insight.
