Deeds are supposed to be performed sincerely for the sake of God Almighty even if they happen to be few in terms of quantity. It is mentioned in some Prophetic traditions that "good deeds" connotes perfect intellect, fear of God Almighty, and being fully aware of Divine Commands even if the good deeds happen to be few in terms of number.
It is narrated from Imam Sadiq (as) as saying that the blessed Verse is indicative of proper acts which are accompanied by worshipping God Almighty and having pure intentions. He further says that preservation of deeds from impurities is harder than performing deeds and sincerely performed righteous good deeds are those whose agent does not expect praise from anyone besides God Almighty. [^3] Thus, the world is the arena of a great trial for all mankind.
Death and life are the means of the trial and the goal behind it is to achieve performing good righteous deeds which are indicative of the development of inward knowledge, sincerity of intentions, and performing any kind of good righteous deeds. In this vein, some Qur’an exegetes maintain that "good deeds" herein connote remembrance of death or preparation for death and the like. In fact they refer to different implications of the general sense of the word.
Since man commits numerous mistakes in such great arena of trial, he should not despair of having committed such mistakes and thereby refrain from striving toward his spiritual growth. The blessed Verse closes with the Divine Promise of Support and Forgiving of sins, saying that God Almighty is Invincible and Oft-Forgiving. He is the Omnipotent Lord Who forgives all repenting believers and His Might and Majesty is accompanied by Mercy and Compassion.
Your sight will return to you in a state of humbleness and exhaustion. The system of Creation is based on Divine Mercy. It is the best system of Creation into which neither defect nor flaw may find its way.
