Not of works, lest any man should boast.  – Ephesians 2:9

Brother, sister, have you gloried in anything you have received? Then bethink you how wrongly you have acted, for you have robbed God of His honor. To glory in man is altogether inconsistent with glorying in God. Depend upon it, every particle of praise we take to ourselves is so much stolen out of the revenues of the King of kings. Will a man rob God? Will a redeemed man rob God? Will a poor sinner snatched from between the jaws of death and hell by undeserved mercy, rob God? Lord have mercy upon us.

When we boast we also leave our truthful position, and every Christian ought to be ashamed to stand anywhere but in the truth. When I confess myself to be weak, helpless, and ascribe all I have to grace, then I stand in the truth; but if I take even the remotest praise to myself, I stand in a lie. The Lord have mercy upon us if we have dared to act falsehood in His presence.

Let us remember, too, that whensoever we prize ourselves highly we are sure to esteem our Lord less…Depend upon it our judgment is very much like a pair of scales: if Christ goes up self goes down; and if self rises Jesus falls in our esteem. No man ever sets a high price upon self and Christ at the same time.

“The more Thy glories strike mine eyes
The humbler I shall be”
