as it is used here, means,

Rescued from the power of sin and darkness, the bondage to sin and death, and receiving the gift of eternal life.

...The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; 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. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Romans 10:8-10

Having 'Saving Faith', means, having faith in Jesus, His Word and His resurrection; being 'born again', having received the gift of 'salvation'.
