That which once was, will be no more. Yesterday will never come again. To-day is passing, and will not return. You may work while it is day; but when you have lost that day, it will not return for you to work in. While your candle burns, you may make use of its light, but when it is done, it is too late to use it.
Richard BaxterSpend your time in nothing which you know must be repented of; in nothing on which you might not pray for the blessing of God; in nothing which you could not review with a quiet conscience on your dying bed; in nothing which you might not safely and properly be found doing if death should surprise you in the act.
Richard BaxterThis is the sanctification of your studies: when they are devoted to God, and when He is the end, the object, and the life of them all.
Richard Baxter
