Fasting is a choice, but it is also obedience. In Matthew 6, Jesus talks about three duties of every Christian: giving, praying and fasting.
And He doesn’t use the word if, He uses the word when. You could choose not to fast this year, but why would you?
Why would you choose to stay where you are when God has so much more for you?
Biblical fasting takes a lot of discipline and strength—strength which you can only receive from God. Your private discipline will bring you
rewards in Heaven, says Matthew 6. When you give God your first through fasting, prayer and giving at the beginning of the year,
you set the course for the entire year.
