"The spiritually negligent involve themselves in much sorrow, neglecting prayer and other means of grace, they seek spiritual ease; but if they are God's children, they do not find it, but sow for themselves abundant thorns of regret and depression. I know of a surety that the diligent Christian is the only happy Christian. True religion is above all other things a business which is not only worth doing, but worth doing well."
