“Lest Satan should get an advantage of us: for we are not ignorant of his devices.” 2 Corinthians 2:11 (KJV
)

“Ah!” says Satan, “It is but a little sin—a little pride, a little worldliness, a little lust, etc. You may commit it without any danger to your soul. It is but a little one; you may commit it, and yet your soul shall live.”

Consider, that there is great danger—yes, many times most danger—in the smallest sins. “A little leaven leavens the whole lump” (1 Corinthians 5:6). If the serpent sneaks in his head, he will draw in his whole body after him. Greater sins do sooner startle the soul, and awaken and rouse up the soul to repentance, than lesser sins do.

Little sins often slide into the soul, breed, and work secretly and indiscernibly in the soul, until they come to be so strong, as to trample upon the soul, and to cut the throat of the soul.

Many are eternally killed and betrayed by the “little sins,” as they call them, that are nourished in their own hearts.

A little hole in the ship sinks it.

A small breach in a dam carries away all before it.

A little stab at the heart kills a man.

A little sin, without a great deal of God’s mercy, will condemn a man!
