God will excuse you if you want to be excused (from the feast, from heaven, from His presence forever). He does not wish to do it, but He will do it. It is easy to say, "I pray thee have me excused." But by-and-by God may take you at your word and say: "Yes, I will excuse you."
And in that lost world, while others who have accepted the invitation sit down to the marriage supper of the Lamb in heaven, you will be crying in the company of the lost: "The harvest is past, the summer is ended, and I am not saved."
