Excuse me? Denial of what? All you have presented is a belief that there is an afterlife. One cannot deny what someone else believes because no one knows if it is true or not. All I can say to you is that you don't know if any such afterlife exists. So my position is to pay attention to what we DO know for certain, and that is that we are here, now. That is all. Nothing more; nothing less. Being here, now, we should then BE here, now, rather than live for some conjecture about a future realm we have no idea exists. Everything in this present moment is complete. All it takes is to be at one with it completely, from one moment to the next, without concern for what one imagines is to come. Yeshu made this clear in his Parable of the Lilies of the Field, sometimes referred to as 'The Wisdom of Insecurity':
Matthew 6:25-34
25 Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
26 Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?
27 Which of you by taking thought can add one cubit unto his stature?
28 And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:
29 And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
30 Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?
31 Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
32 (For after all these things do the Gentiles seek for your heavenly Father knoweth that ye have need of all these things.
33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
34 Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
What a novel idea: to live in the present where you actually find yourself to be all the time.
