Conclusion

That the Prophet Jesus (as) will be sent back to earth for a second time by Allah is surely Divine glad tidings to all humanity. Islamic moral values will prevail with his second coming. 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, the Prophet Jesus (as) will wholeheartedly communicate 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 the Prophet Jesus (as) will protect and guide all believers, the believers must also give their wholehearted support to the Prophet Jesus (as) and help him in the services he renders for the sake of Allah.

Any idleness with regard to welcoming such an important guest will of course be morally unacceptable. No one, who has faith in Allah's verses, and is aware of world developments and the signs of the end times, can decide not to prepare for this blessed visitor. Those who follow the messengers of Allah, who provide them sincere support and adopt the revealed values brought by them 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: 10-11)
