Note 3 at 1 Cor. 15:31: This verse is often quoted as Paul dying to sin daily, but that is not what this is saying. The context makes it very clear that Paul is speaking of physical death. He is saying he faces death on a daily basis. It would be stupid to do so if there were no resurrection. If there were no resurrection and no eternal destiny at stake, we should just "party" and forgo the hardships (v. 32).

The Bible does not teach a daily death to sin. It clearly states that we died unto sin once just as Jesus did (Rom. 6:1-11), and that we should continually reckon that to be so (see note 3 at Rom. 6:2, p. 776; see note 8 at Rom. 6:6, p. 778).
