So it is not finished.
The general redemption is finished. The application of the redemption to you as an individual most certainly isn't finished. If it had been finished on Calvary, there would clearly have been no need for you to believe, repent, be baptized, pray, read Scripture, go to church ... etc.
Not for you. Paul didn't think it was over for him while alive, either
"I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified." (1 Cor 9:27)
Christ calls us to be disciples. Read the Gospel of Mark if you are interested in the NECESSITY of becoming servants to others. Christ tells us over and over we must become like Him.
