God, through His perfect wisdom, created us for a purpose. And it is those who believe in God, remember Him always, and show thankfulness to Him for all His blessings that realise life’s true purpose and meaning. And the purpose of life is simple:
And I (God) did not create the jinn and mankind except to worship Me. (Quran 51:56)
God created us to test us, to see who would choose belief in Him over disbelief, to see who would devote his life to praising and showing thanks to Him over being negligent and arrogant towards Him, to see who would choose a life of righteousness over evil, and to see who would choose guidance over misguidance. Moreover, God would not leave His creation without guidance. So upon us is to seek the truth and find the guidance of God before death should overtake us. One might ask why would not God just show everyone a clear sign that would force all people to believe in Him and follow His guidance.
The Quran answers this question in the following verse:
Do they [then] wait for anything except that the angels should come to them, or your Lord should come, or that there come some of the signs of your Lord (i.e., portents of the Last Hour e.g., arising of the sun from the west)? The Day that some of the signs of your Lord will come, no good will it do to a person to believe then, if he believed not before, nor earned good (by performing deeds of righteousness) through his Faith. Say, “Wait. Indeed, we [also] are waiting.” (Quran 6:15
Faith is precious because it requires diligence and effort. And those who pass the test of life do so because of their faith. They believe in and worship God even though they don’t see him. They seek out and follow His guidance and perform righteousness even though their whims and desires may persuade them to do otherwise. And God has promised an eventual benefit and reward for faith and righteous deed, as the Quran says:
Indeed, they who have believed and done righteous deeds and humbled themselves to their Lord – those are the companions of Paradise; they will abide eternally therein. (Quran 11:23)
This benefit is not restricted to the Afterlife. Rather, realizing our purpose in life is a means to eradicating the sense of emptiness and disarray we may suffer from in life, thereby instilling inner peace and contentment in our lives. And only faith in God supplies us with the hope and spiritual strength we require to overcome all of life’s adversities, the greatest of them being death. Thus, the fruits and benefits of faith are experienced both in our present life and in our eventual life to come.
Those who have believed and whose hearts are assured by the remembrance of God. Unquestionably, by the remembrance of God hearts are assured. (Quran 13:2
Whoever does righteousness, whether male or female, while he is a believer – We will surely cause him to live a good life, and We will surely give them their reward [in the Hereafter] according to the best of what they used to do. (Quran 16:97)
Faith however requires that we following the guidance God has sent down for mankind to follow. Since how can one know the requirements of faith, worship, and obedience to God if one does not know His guidance? So upon us is to seek the true guidance.
Salaam.
