The likeness of ‘Isa in Allah's sight is the same as Adam. He created him from earth and then He said to Him: "Be!" and he was. (Surah Al ‘Imran: 59)
As mentioned in the verse, Allah gave the command "Be!" to Adam and he was accordingly created. The way Jesus (as) came into existence for the first time also occurred in the same way although he had a mother. Adam had no parents and neither will Jesus (as) at his second coming.
In the history of mankind, that Jesus (as) will be sent back to earth for a second time by Allah is surely a divine favour to all humanity. Only a minority of people will enjoy this occasion. He will then be a blessed "saviour" sent to all mankind. Indeed, in times when violence and disorder were increasingly experienced in the world, human beings begged a "helper" from Allah. Accordingly, Allah responded to their plea:
What reason could you have for not fighting in the Way of Allah - for those men, women and children who are oppressed and say, "Our Lord, take us out of this city whose inhabitants are wrongdoers! Give us a protector from You! Give us a helper from You!"? (Surat an-Nisa: 75)
As mentioned earlier, the "saviour" in our time is the penetration of the Qur'anic values to our souls and society. Upon his second coming, Jesus (as) will wholeheartedly adhere to these revealed values favoured by Allah and strive purely to spread them to people all over the world.
The knowledge of unseen and future events is something only known to Allah. Yet, it is certain that those who expect this blessed period and this person must at that time undertake important obligations. Just as Jesus (as) will protect and guide all believers, the believers will also have to give wholehearted support to Jesus (as) and help him in the services he renders for the sake of Allah. This time, in other words, during his second coming, believers should never make him ask again, "Who will be my helpers to Allah?" (Surah Al ‘Imran: 52) Otherwise, one will feel deep regret and torment both in this world and hereafter. Allah clearly threatens those who are ungrateful:
Then we sent our Messengers one after another, at intervals. Each time its Messenger came to a community they called him a liar so We made them follow one another too and turned them into myths and legends. Away with the people who have no faith! (Surat al-Muminun: 44)
On the other hand, those who follow him, who provide him sincere support and adopt the revealed values brought by him may well hope to earn the good pleasure, mercy and eternal paradise of Allah. This is a definite promise and good tidings given by Allah:
Allah has sent down a reminder to you, a Messenger reciting Allah's Clear Signs to you to bring those who have faith and do right actions out of the darkness into the Light. Whoever has faith in Allah and acts rightly, We will admit him into Gardens with rivers flowing under them remaining in them timelessly, for ever and ever. Allah has provided for him excellently! (Surat at-Talaq: 11)
We are grateful to Allah, the Almighty, Who will honour such of His slaves as He wills on such a great occasion as the second coming of Jesus (as) and grant them this important opportunity to gain merit for their lives in the hereafter.
