Knight of Pentacles

A person on a horse, wearing a suit of armor with the face visor open.  The horse is a rugged, sturdy - this horse is not a race horse but more like a working horse which is able to carry heavy loads.  This would be a symbol for consistency, stable, even-keeled.  The horse is black symbolizing regeneration or change.  I feel this is verified by the hoed rows that are in the field behind the knight.  Seed is planted, it is transformed into some form of life to serve another purpose.

The knight appears to be presenting the coin/orb/globe to someone - he's in a posture of humility.  The armor here I feel is sort of like a shell or skin on a seed - we see the visor opened on his head which to me symbolizes being open to new things.  With the visor open he can see clearer, he can see the peripheral, and part of his mind is open to the Spirit.

So perhaps this card is really telling us that in order for us to grow we need to die to the self, shed off the old skin/armor and allow the Spirit to come in so that it's work can be done through us.
