God does not need anything from us because he is self-sufficient
I agree. God has no needs, only humans and other animals have needs. Whatever God gives us is only for our own benefit.
“Regard thou the one true God as One Who is apart from, and immeasurably exalted above, all created things. The whole universe reflecteth His glory, while He is Himself independent of, and transcendeth His creatures.”
“Consider the mercy of God and His gifts. He enjoineth upon you that which shall profit you, though He Himself can well dispense with all creatures.”
Gleanings, p. 140
“The one true God, exalted be His glory, hath wished nothing for Himself. The allegiance of mankind profiteth Him not, neither doth its perversity harm Him. The Bird of the Realm of Utterance voiceth continually this call: “All things have I willed for thee, and thee, too, for thine own sake.”
If you wish to know what after life like. You can read the holy books you might get hints how after life will be like.
“Death proffereth unto every confident believer the cup that is life indeed. It bestoweth joy, and is the bearer of gladness. It conferreth the gift of everlasting life.”
Gleanings, p. 345
But what does that actually mean? How do we know if we are a confident believer? What will joy and gladness consist of? What is everlasting life?
I do not believe everlasting life means living forever, since I believe that all souls will continue to exist forever, but not everyone will have everlasting life, which is nearness to God, but how will that play out in the afterlife?
There are hints in the holy books but there is no real information. God keeps the mystery of the afterlife under His hat. We are told that one reason the afterlife has not been described in the holy books is because we could never comprehend a world that is so different from this wold.
“As to those that have tasted of the fruit of man’s earthly existence, which is the recognition of the one true God, exalted be His glory, their life hereafter is such as We are unable to describe. The knowledge thereof is with God, alone, the Lord of all worlds.”
Gleanings, pp. 345-346
