According to the Bible, there are three duties of every Christian: give, pray and fast. 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.
1 TIMOTHY 2:1-2
“I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men; For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty.”
“I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, [which is] your reasonable service.”
“But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.”
“[Is] not this the fast that I have chosen to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke?”
