The Four Cups represent G-d's four promises to his people:

  1. Take them out of Egypt.
  2. Deliver them from bondage.
  3. Redeem them with an outstretched hand.
  4. Acquire them to be G-d's chosen people.

Even though we are no longer in Egypt living in slavery, these promises can still apply to our lives as G-d stays faithful to us in our hardships in life. In a simplified form, these cups can be said to represent:

  1. Sanctification
  2. Deliverance
  3. Redemption
  4. Salvation
