love of allah ta'ala

Q: Please advise me as to how/what should a teenager do in today's day and age to protect himself/herself from the fitnahs all around. What should be done to instill the love of Allah in one's heart ? 

Q: I have come across an aayaat or Ahaadith that state the following: Allah loves it when.....Allah loves those who are...Allah loves this....Allah loves that if one.....etc. So My question is:

1.) What are the virtues or reward in doing those things that Allah loves?

2.) When you do those things that Allah loves, will you get his mercy and pleasure?
