"Then the Lord said to Aaron, 'You and your sons are not to drink wine or other fermented drink whenever you go into the tent of meeting, or you will die. This is a lasting ordinance for the generations to come, so that you can distinguish between the holy and the common, between the unclean and the clean'" - Leviticus 10:8.
The Lord forbade the priests, who were the leaders in Israel, to partake of any alcoholic beverages before they went to work in the tent of meeting. This was not because the Lord was against alcohol altogether, but rather so their judgment would not be impaired when they were dealing with spiritual things. In other words, they were to take their work seriously and be motivated by a desire to serve the Lord. Leaders today must also be careful not to self-medicate themselves to help them get through the anxiety and pressures of work, which can take the form of addictive substances like food, medicine, alcohol, or almost any other activity that will help them escape their work rather than engage it.
LEADERSHIP STEP: Your Step today is to do an honest evaluation of your recent approach to work and your leadership role. If it's strictly for the money, then you may be a candidate for adopting lifestyles and habits that help you get through your workday because of boredom or anxiety. Are you exercising regularly? How's your weight? Are you engaging in any habit that's helping you get through the day but preventing you from giving your best efforts at work, or from resting sufficiently when you aren't working?
