Why the law was our schoolmaster to bring us to Christ, that we might be justified by faith.
You never saw a woman sewing without a needle. She would come but poor speed if she only sewed wi' the thread. So, I think, when we're dealing with sinners, we maun aye put in the needle of the law first; for the fact is, they are sleepin' sound, and they need to be awakened up wi' something sharp. But, when we've got the needle o' the law fairly in, we may draw as long a thread as you like o' gospel consolation after it.
