Charles H. Spurgeon on Psalms 139:4

For there is not a word in my tongue, etc. How needful it is to set a watch before the doors of our mouth, to hold that unruly member of ours, the tongue, as with bit and bridle. Some of you feel at times that you can scarcely say a word, and the less you say the better. Well, it way be as well; for great talkers are almost sure to make slips with their tongue. It may be a good thing that you cannot speak much; for in the multitude of words there lacketh not sin. Wherever you go, what light, vain, and foolish conversations you hear! I am glad not to be thrown into circumstances where I can hear it. But with you it may be different. You may often repent of speaking, you will rarely repent of silence. How soon angry words are spoken! How soon foolish expressions drop from the mouth! The Lord knows it all, marks it all, and did you carry about with you a more solemn recollection of it you would be more watchful than you are. —Joseph C. Philpot.
