This is something I have been reading and praying about recently.. fasting
I am a fairly new Christian, and I didn't know anything about it..
There are several verses that support fasting..
One of them being Matthew 6:16-18 : "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.
Notice it says when you fast..
I believe Christians should fast to grow closer to the Lord,
or if they have an issue going on that they are seeking guidance
about.. there are a number of reasons.
I believe it's something you should pray about though,
and the Lord will give you guidance about it..
