The Lord is not slack concerning his promise, as some men count  slackness; but is longsuffering to us-ward, not willing that any should  perish, but that all should come to repentance. I Peter 3:9  The promise of a Saviour has been fulfilled in the virgin birth, sinless life, vicarious death, and glorious resurrection of the Lord Jesus Christ.  Your part is to exercise personal faith with sincere heart prayer.

Romans 10:9-13 "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.  For the scripture saith, Whosoever believeth on him shall not be ashamed.  For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.  For whosoever shall call upon the name of the Lord shall be saved."
