Knowledge is Forever (Stories for kids by Maulana Room)

An undeniable reality is that permanent happiness cannot be achieved except by believing in God - The Creator - and following His guidance. Since it is He who created mankind, He is the one who knows what pleases and benefits them, just as he knows what saddens and harms them. A number of psychologists have affirmed that only a religious person lives with true content and serenity. So if believing in God leads to ultimate happiness, then how can this be achieved?
There are numerous religions and a variety of creeds. However, their critical differences in core issues make it impossible for all of them to be correct. So which is the correct religion? What is the correct creed that God requires us to believe in and in the end pleases Him? And which one of these creeds guarantees us happiness in this life and in the hereafter?
Before answering these questions, a criterion must first be established to be used as a basis for correctly determining the true religion. I firmly believe that all sensible people will agree that a religion is not deemed correct simply due to the fact that one was raised in that religion, had parents that adhered to it, or lived in a society that practiced it. Rather a religion's accuracy and authenticity are based upon substantial evidence and firm intellectual proofs. Intellect, the distinguishing factor between mankind and animals, must be applied when studying the issue of religion, which is undeniably the most important and gravest of all matters.
