Christian faith is evidence based faith, the evidence being the historic eyewitness testimony to the miracles of Jesus and his apostles. Jesus said of his miracles, “Do not believe me unless I do what my Father does.” John 10:37 Why did Jesus say we should believe in him? "Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the miracles themselves." John 14:11 And likewise John writes as to the purpose of the miracles. "Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name." John 20:30,31 Under duress John the Baptist questioned his faith and asked of Jesus, "Are You the Coming One, or do we look for another?" Jesus answered and said to them, "Go and tell John the things which you hear and see: "The blind see and the lame walk; the lepers are cleansed and the deaf hear; the dead are raised up and the poor have the gospel preached to them." Mt 11:4,5
