While "word of mouth" is the best advertisement, it should not be an excuse to sit back and wait for students to flow into your classrooms. Recruitment, aggressive recruitment, should always be the "modus operandi." Actually when enrollment is strong, marketing be even stronger. It helps to protect during the lean times. Recruitment, however, even aggressive recruitment won't assure fiscal strength unless tuition, spending, and salaries, essentially the entire budget is in balance.
Without oxygen, your body will die. And without "spiritual oxygen," your spirit cannot come alive. Only the Lord can give life to your body. And only the Holy Spirit can give "spiritual oxygen" to your spirit. The Christian life is as miraculous as breath itself. Receiving life-giving oxygen into your spirit is as easy as taking your first breath after being born. It just happens.
