Charles H. Spurgeon on Psalms 39:9

I was dumb, I opened not my mouth; because thou didst it. This had been far clearer if it had been rendered, "I am silenced, I will not open my mouth." Here we have a nobler silence, purged of all sullenness, and sweetened with submission. Nature failed to muzzle the mouth, but grace achieved the work in the worthiest manner. How like in appearance may two very different things appear! silence is ever silence, but it may be sinful in one case and saintly in another. What a reason for hushing every murmuring thought is the reflection, "because thou didst it."! It is his right to do as he wills, and he always wills to do that which is wisest and kindest; why should I then arraign his dealings? Nay, if it be indeed the Lord, let him do what seemeth him good.
