"All should guard the senses,
lest Satan gain victory over them;
for these are the avenues of the soul."
Counsels For The Church p.166, E.G.W.
Guard the avenues to your mind.....
And be not conformed to this world:
but be ye transformed by the renewing of your mind,
that ye may prove what is that good, and acceptable, and perfect, will of God.
Romans 12:2
Because someone is seeking access.....
Be sober, be vigilant; because your adversary the devil,
as a roaring lion, walketh about, seeking whom he may devour:
1 Peter 5:8
