Wikipedia says faith is "belief that is not based on proof". As christians faith has so much to do with our religion. We have to have faith that Jesus is Gods one and only son that died for our sins, to be saved. Wikipedia is somewhat right faith does have to do with beliefs, but the second part says "that is not based on proof". We do have proof that God is real. We do have proof that Christianity is the way to live. One simple book is our proof, the Bible. The bible says in the book of Ephesians chapter 4 verse 5 "One Lord, one faith, one baptism". This means us as christians having a strong faith is just as important as us believing that there is only one Lord.
