In "Bhagwat Gita", Lord Krishna Says that if a person is devoted to God only then God rescues that person from all the miseries of life. If you have strong faith in God then God shall keep you away from all harm and shall watch over your life. He shall guard you from every evil & shall protect you always in life. Lord says:
"ye tu sarvani karmani
mayi sannyasya mat-parah
bhavami na cirat partha
"Those people, who worship Me by surrendering all their activities unto Me, are always devoted to Me, always meditate upon Me, Having always fixing their minds upon Me, O Parth - to them, I swiftly rescue from the miseries of life & also from the cycle of birth and death i.e always protect that devotee."
"ananyas cintayanto mam
ye janah paryupasate
"Sri Krishna said: But those who always worship Me with exclusive devotion, meditating on My transcendental form—to them I provide what they lack, and I protect what they have."
Jai Shri Krishna
