"The less the temptation is to sin, the greater is that sin."
"When Satan says it is but a little one, do thou answer, that oftentimes there is the greatest unkindness showed to God's glorious majesty, in the acting of the least folly, and therefore thou wilt no displease thy best and greatest friend, but yielding to his greatest enemy."
"There is a great danger, yea, many times most danger, in the smallest sins.... Greater sins do soon startle the soul, and awaken and rouse up the soul to repentance, then lesser sins."
Thomas Brooks, Precious Remedies Against Satan’s Devices, Banner of Truth Trust, pgs 41-42)
