We are all totally depraved, but through unconditional election and limited atonement G-d saves some who cannot reject this (which means they cannot claim glory for the work of 'accepting') and He keeps them through it by Perserverance.
If you reject one of these points, you reject all of TULIP
Then this G-d of yours isn't the God revealed in scripture. And I doubt you win converts from the lost with your message, but instead try to raid the churches around you. One of the prominent OPC posters on FR once admitted she didn't know anyone who converted from non-Christian to Calvinist.
Here is the Gospel:
30Then he brought them out and said, "Sirs, what must I do to be saved?" 31And they said, "Believe in the Lord Jesus, and you will be saved, you and your household." 32And they spoke the word of the Lord to him and to all who were in his house. 33And he took them the same hour of the night and washed their wounds; and he was baptized at once, he and all his family. 34Then he brought them up into his house and set food before them. And he rejoiced along with his entire household that he had believed in God." - Acts 16
You will note they did NOT reply, "If God saves you, you will believe!"
