Fasting was a part of praying. When someone is in distress or mourning, they prayed.
Jesus made a statement about those who are walking around praying at a event, making themselves look as if they are sadden by something or someone at these community events.
What Jesus meant by going into your closet to pray, He's referring to keep it within you, like pray from our soul that He can hear our thoughts or our emotions.
I know it's wonderful to be smacking on a nice juicy steak while praying for others while they are in pain. But you can only focus on one thing at a time.
I guess just put off the prayer until you are full.
Isaiah 58
“Shout it aloud, do not hold back. Raise your voice like a trumpet. Declare to my people their rebellion and to the descendants of Jacob their sins. For day after day they seek me out; they seem eager to know my ways, as if they were a nation that does what is right and has not forsaken the commands of its God. They ask me for just decision
s and seem eager for God to come near them. ‘Why have we fasted,’ they say, ‘and you have not seen it? Why have we humbled ourselves, and you have not noticed?’ “Yet on the day of your fasting, you do as you please and exploit all your workers.
Matthew 6:16
“When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show others they are fasting. Truly I tell you, they have received their reward in full.
Philippians 3:19
Their destiny is destruction, their god is their stomach, and their glory is in their shame. Their mind is set on earthly things.
