The Trojan horse

(Thomas Watson, "The Lord's Prayer")

"Deliver us from evil." Matthew 6:13

In this petition, we pray to be delivered from the
evil of our heart, that it may not entice us to sin.

The heart is the poisoned fountain, from whence
all actual sins flow. "For from within, out of the heart
of man, come evil thoughts, sexual immorality, theft,
murder, adultery, coveting, wickedness, deceit,
sensuality, envy, slander, pride, and foolishness."
Mark 7:21-22.

The cause of all evil lies in a man's own bosom—all
sin begins at the heart. Lust is first conceived in the
heart—and then it is midwifed into the world. Whence
comes rash anger? The heart sets the tongue on fire.
The heart is the shop where all sin is contrived and
hammered out.

The heart is the greatest seducer "Each one is
tempted when he is carried away and enticed by
his own lust." James 1:14. The devil could not hurt
us—if our own hearts did not give consent. All that
he can do is to lay the bait—but it is our fault to
swallow it! How needful, therefore, is this prayer,
"Deliver us from the evil of our hearts!"

It was Augustine's prayer, "Lord, deliver me from
that evil man—myself!"

Beware of the bosom traitor—the flesh. The heart
of a man is the Trojan horse—out of which comes
a whole army of lusts! O let us pray to be delivered
from the lusts and deceits of our own heart!
