Fasting is a sacred and special sacrifice; it is for the Lord, not for human approval or notice. In Matthew 6:16-18, Jesus cautions those who choose to fast for human admiration and approval, "When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show men they are fasting. I tell you the truth, they have received their reward in full. But when you fast, put oil on your head and wash your face, so that it will not be obvious to men that you are fasting, but only to your Father, who is unseen; and your Father, Who sees what is done in secret, will reward you."

Please understand the spirit of Jesus' message. He is not saying that absolutely no one should know when we are fasting. In fact, it is very important to have a trusted Christian friend or a network of Christian friends who can pray for you while you are fasting. Jesus is cautioning against fasting for the approval and notice of man, just as He cautions against giving for sheer spectacle.

In the account of Jesus' desert temptation, both Matthew and Luke record that, at the end of His 40-day fast, "He was hungry". Jesus, fully man and fully God, experienced every emotion and sensation as His children do: hunger, weakness, tiredness. The significant difference, of course, is that even in His weakened state, Jesus perfectly avoided temptation and sin. He did so by completely relying on the Word of God. Jesus knows that you will feel weak, hungry, sick, and even afraid at times, but He will sustain you in ways you never thought possible. To receive that sustenance, you must persevere in trust and faithfulness.

"Jesus answered, 'It is written: Man does not live on bread alone, but on every word that comes from the mouth of God.' " (Matthew 4:4)
