The best part to make your faith strong is Pray.
When you feel you are all alone in the world and there is nobody to talk. Believe that Jesus is your friend and talk to him.
Your Prayer may not be of words of orthodox church summarized together.
Just Open your heart and talk……
Pray for your friends, Pray for the World, Pray for Neighbors…..Pray aloud.
and this peace of mind will solve your problems. The faith as as big as a mustard seed
