Athiesm (sp?) is a faith. It is just like Christianity, Islam or Hinduism. While there is one right faith, we do not know which one that is. So, I'm not going to tell you that Christianity is 100% the right choice...but I will tell you to go with what your heart and soul tells you.
Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me." (John 14:6)
"Trust in the Lord with all your heart, and lean not on your own understanding; in all your ways acknowledge Him, and He shall direct your paths." (Proverbs 3:5-6)
Forever praise Him
