1 Peter 5:8 - Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:

The helment of Salvation -

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.

^{John 10:10} The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.

Sin

2 Timothy 2:15

¹⁵ Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
