CPR only works when something is alive.
Let me make it easier.
So far, the Church has buried all Her undertakers.
And Her Founder rose from the dead.
That is incorrect. CPR is only applied after the person is dead. One does not apply CPR to a patient with a heartbeat.
Please ... find a CPR course at your place of employment, your church, your local fire department, whatever ... learn and get yourself certified.
