Had it been simply like this, it would be easy for John Doe or someone else to steal from you by forging transactions from your address.

Since your cold storage Bitcoin wallet was created offline, you will be required to first transfer the funds from the cold storage to an online wallet before transacting.

A good example of a suitable Bitcoin wallet is Bitcoin Unlimited, which is Bitcoin-run, or Blockchain. Once the funds are in your Bitcoin wallet, they can then be used in transactions without further processing.
