إِنَّ ٱلَّذِينَ ءَامَنُوا وَعَمِلُوا ٱلصَّٰلِحَٰتِ يَهْدِيهِمْ رَبُّهُم بِإِيمَٰنِهِمْ ۖ تَجْرِى مِن تَحْتِهِمُ ٱلْأَنْهَٰرُ فِى جَنَّٰتِ ٱلنَّعِيمِ

Literally, ‘On account of their faith, God will lead them towards the goal of Paradise.’ This shows that Faith is guidance for man; it prevents him from taking wrong paths and makes him tread the right way until it leads him to the real goal. Faith is discovery of God. The thread of knowledge comes within the grasp of one who is blessed with faith. He becomes capable of starting his thinking from the right place on all matters. Never allowing his thoughts to err, he attains correctness in his thinking. Furthermore, belief in God is not simply acceptance of a bookish philosophy; it is belief in God Who is alive and Who is going to finally assemble all human beings before Him to take a final reckoning. In this way, Faith inculcates in man a sense of anxiety or apprehension about his future fate and this makes him extremely serious. He is forced to look at all his actions in the light of their being right or wrong, so that he may adopt only the right direction. In this way, Faith provides man with the right way of thinking as well as the power to distinguish between right and wrong, which acts as his permanent practical guide. The Paradise of the Hereafter is for those who have, in this world, proved themselves to be deserving of it. The Hereafter is a place where one will directly experience and become directly immersed in the glories of God. So, the opportunity to live in Paradise will be given only to those who, in this world, had immersed themselves in the indirect manifestations of the glories of God. In the Hereafter, human hearts will be full of well-wishing and peace-desiring for each other. So, only those who, in this world had proved that in their hearts they had only such feelings for others, will find their abode in Paradise.
