Yes, but it is also a Contract between the Servant and the one maintaining that magical source. You would be given three Command Seals - three spells, essentially, in which you could command anything of me and I would be forced to obey, no matter the order.

Including taking my own life or forcing me to carry out something I found distasteful. In that sense, your offer is essentially the same as telling me to place my entire being into your hands.
