Hey.
Allaah Almighty doesn't need nothing from us, as He is self sufficient.
However, we are Allaah's creation and we cannot survive without the help of Allaah. Allaah is the One who provides for us, in every matter i.e. provides us with food, air, health etc. and if Allaah willed - none of this would ever reach us and we would be destroyed.
Allah! There is no god but He,-the Living, the Self-subsisting, Eternal. No slumber can seize Him nor sleep. His are all things in the heavens and on earth. Who is there can intercede in His presence except as He permitteth? He knoweth what (appeareth to His creatures as) before or after or behind them. Nor shall they compass aught of His knowledge except as He willeth. His Throne doth extend over the heavens and the earth, and He feeleth no fatigue in guarding and preserving them for He is the Most High, the Supreme (in glory). (Qur'an 2:255)
I understand that we need servitude to him in order to evolve ourselves and
survive the death process.
Every soul shall have a taste of death in the end to Us shall ye be brought back. (Qur'an 29:57)
We as muslims believe that we will die, whether we are muslims or not. But we believe that this life is a test, will a person submit to God or will the person reject God?
Once the person dies, their time is up and if they never believed in God - they will be punished severely for rejecting the One who created him/her.
But if the person believed and obeyed in the God that created him/her - they will be rewarded with paradise, because they believed in the signs that Allaah gave, and they will be rewarded for what they did in this world (for example, gave charity, helped the needy, worshipped Allaah etc.)
This is why Allaah Almighty says in the Qur'an:
Is there any Reward for Good - other than Good?
(55:60)
"Say, 'Shall I bring your attention to things far better than those? For the righteous are gardens in nearness to their Lord, with rivers flowing beneath, eternal therein, with pure companions and the good pleasure of Allah. For within Allah's sight are all His servants – especially those who say, "Our Lord, we have indeed believed, so forgive us our sins and protect us from the agony of the Fire." Those who are patient, are truthful, who worship devoutly, who spend in the way of Allah and who prays for forgiveness in the pre-dawn hours.'"
[ali'-Imran, 3: 15-17]
"Allah will admit those who believe and work righteous deeds to gardens beneath which rivers flow, they shall be adorned with bracelets of gold and pearls, and their garments therein will be silk. They have been guided in this life to good speech, and they have been guided to the path of Him, the All Praised."
[Hajj, 22: 23-24]
