Fasting can be defined as willfully abstaining or reducing the intake of food or water for a period of time. It has got to do with abstaining from things that give an individual pleasure which sometimes include sex among married couples.
During the time of fasting, we deny ourselves of all that gives us pleasure physically and commune with the Lord. As we become lighter physically, spiritual intimacy with the Lord is deepened. Christians should not engage in fasting only when they need something from the Lord but as a means of strengthening their relationship with the Lord.
From our reading today, we realise that Esther and the other Jews fasted and prayed before Esther could go into the presence of the king and obtain favour. Likewise, Jesus challenged His disciples in Mark 9:29 that it takes fasting and prayers to be able to make certain strides when it comes to matters of the spiritual.
Research has also shown that fasting has a lot of health benefits such as lower blood pressure, weight loss among others.
As believers, we need not downplay the importance of fasting in our Christian walk. We must have a consistent fasting habit which will help in deepening our spirits and bring along with it many health benefits.
