Let each one examine his own work. Then he can take pride in himself and not compare himself with someone else.

Urgency of Self-Examination
C. H. Spurgeon.

Galatians 6:4
But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another.

Remember that the time you have for self-examination is, after all, very short. Soon thou wilt know the great secret. I may not say words rough enough to rend off the mask which thou hast now upon thee; but there is one called Death who will stand no compliment. You may masquerade it out to-day in the dress of a saint; but Death will soon strip you, and you must stand before the judgment-seat after Death has discovered you in all your nakedness, be that naked innocence or naked guilt.
