Is not just head knowledge.
Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
It is not temporary faith to get you through a crisis.
SAVING FAITH is:
Trusting in Jesus Christ alone for eternal life.
9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
