Salvation

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.

The Armor of God

Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.  For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.  Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.  Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;  And your feet shod with the preparation of the gospel of peace;  Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.  And take the helmet of salvation, and the sword of the Spirit, which is the word of God:  Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
