This is not going to please you, but a cursory inspection of the context reveals the answer. Here is the context... There are 3 paragraphs under 3 heading descriptions in the NKJV. The verse in question is in the 3rd paragraph. Here is the text:
The Risen Christ, Our Hope
12 Now if Christ is preached that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, then Christ is not risen. 14 And if Christ is not risen, then our preaching is empty and your faith is also empty. 15 Yes, and we are found false witnesses of God, because we have testified of God that He raised up Christ, whom He did not raise up—if in fact the dead do not rise. 16 For if the dead do not rise, then Christ is not risen. 17 And if Christ is not risen, your faith is futile; you are still in your sins! 18 Then also those who have fallen asleep in Christ have perished. 19 If in this life only we have hope in Christ, we are of all men the most pitiable.
The Last Enemy Destroyed
20 But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep. 21 For since by man came death, by Man also came the resurrection of the dead. 22 For as in Adam all die, even so in Christ all shall be made alive. 23 But each one in his own order: Christ the firstfruits, afterward those who are Christ’s at His coming. 24 Then comes the end, when He delivers the kingdom to God the Father, when He puts an end to all rule and all authority and power. 25 For He must reign till He has put all enemies under His feet. 26 The last enemy that will be destroyed is death. 27 For “He has put all things under His feet.” But when He says “all things are put under Him,” it is evident that He who put all things under Him is excepted. 28 Now when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.
Effects of Denying the Resurrection
29 Otherwise, what will they do who are baptized for the dead, if the dead do not rise at all? Why then are they baptized for the dead? 30 And why do we stand in jeopardy every hour? 31 I affirm, by the boasting in you which I have in Christ Jesus our Lord, I die daily. 32 If, in the manner of men, I have fought with beasts at Ephesus, what advantage is it to me? If the dead do not rise, “Let us eat and drink, for tomorrow we die!”
The New King James Version (1 Co 15:12–32). (1982). Thomas Nelson.
The first paragraph takes issue with one of the doctrines that the Corinthian believers were taking seriously, which is that the dead are not raised to life. Paul points out many things that are not true if in fact the dead are not raised.
The second paragraph, starting with verse 20, begins with a bold statement that Christ has indeed been raised from the dead. He then states the chronological order of various things that will occur between now and the end of this age. It ends with all things being put under Jesus' feet and eventually all things being put under God, "that God may be all in all".
The Third paragraph, starting with verse 29, re-addresses the logical conclusions that may be drawn from the contrary view. If there is no resurrection, baptism is pointless. If there is no resurrection, why do we "stand in jeopardy every hour?" Then Paul "boasts" about dying daily, identifying himself as a fool for placing himself in jeapordy ever hour if in fact the dead are not raised. Then He gives an example of his dangerous expliots that would be of no value if the dead were not raised. He concludes the paragraph with the only logical conclusion possible, "If the dead do not rise, 'Let us eat and drink, for tomorrow we die!'”
You probably have already locked yourself into your position on verse 31 and are probably not swayed by my analysis of the context, but I hope you're able to adapt. It shows clearly that it has nothing to do with inviting the Holy Spirit into your heart every morning. Hopefully, you can find your way past that misconception of the Holy Spirit's presence as well.
