Son, if there is anything which you cannot comprehend do not repudiate it, but you should meditate over it and attribute your failure to understand it to the limitations of your intellect. It may be appreciated that when you are born you are devoid of understanding, and knowledge comes to you steadily as you grew up. Even when grown up, it cannot be said how many things there are still, of which you are ignorant. There are things, which excite your wonder, but knowledge about them dawns on you gradually. Therefore your attachment should be to that Being who has created you, and who has given you sustenance. Your prayers should be for Him, and you should resign yourself to His Will. Son, no one has taught about God as the Holy Prophet. Make him your guide, and seek your salvation through him.
"When a person dies, his works end, except for three: ongoing charity, knowledge that is benefited from, and a righteous child who prays for him."
Prophet Mohammed (PBUH)
"The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him."
Sunan Ibn Mājah
"Every day two angels come down from Heaven and one of them says, 'O Allah! Compensate every person who spends in Your Cause,' and the other (angel) says, 'O Allah! Destroy every miser.'"
Sahih Bukhari
