What do you mean? Of course he will. This is basic doctrine. Look no further that the Nicene Creed:
He will come again in glory to judge the living and the dead, and his kingdom will have no end.
Will I see his return before I am laid into my temporary grave? I have my doubts. But like the story of the 10 virgins, I should always be prepared for his return, and I am. I am repentant and baptized in the Name. I am prepared for his arrival at any moment, which will be like a thief in the night.
