"Life is seed time. Of all men it may be said, 'They have sown.' Prudent men put the question, 'What will the harvest be?...Vicious men sow their wild oats, and we need not say what they reap. The debauched, drunken and profligate around us, bearing already in their own persons the first fruits of the fearful harvest of transgression." (From Spurgeon's sermon notes)
