This may be a bit harsh but please know that i am going to say this with all the love and sincerity of Christ. When a person dies his spirit returns to the Lord and there he awaits the judgment. Nothing can be done for him after that because his purpose as "man" is complete. The commandments of God are not meant for the dead but for the living; hence salvation is for the living. If a person rejects Christ while alive then it is a surety that Christ will reject him on the day of judgment. The best thing you can do now is to pray for those who are here who are still alive. The dead cannot hear you because they no longer have a consciousness of this world...they are not omniscient either and cannot be in two places at once. The chapter of their life has already been closed and there is no turning back for them....the Bible says so
A person will not be judged for what he did when he is dead but rather what he did when he was alive. NO ONE CAN BE REDEEMED AFTER DEATH AND PRAYING FOR THEIR SOULS IS POINTLESS!!!
Ecclesiastes 12
1Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;
2While the sun, or the light, or the moon, or the stars, be not darkened, nor the clouds return after the rain:
3In the day when the keepers of the house shall tremble, and the strong men shall bow themselves, and the grinders cease because they are few, and those that look out of the windows be darkened,
4And the doors shall be shut in the streets, when the sound of the grinding is low, and he shall rise up at the voice of the bird, and all the daughters of musick shall be brought low;
5Also when they shall be afraid of that which is high, and fears shall be in the way, and the almond tree shall flourish, and the grasshopper shall be a burden, and desire shall fail: because man goeth to his long home, and the mourners go about the streets:
6Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern.
7Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
Ecclesiastes 9:5 (King James Version)
5For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.
