Fasting
The practice of fasting is to not eat food and/or drink for a set period of time. This was something done by many people of God throughout history including Jesus himself. The following are some reasons to fast:
Directed by the Holy Spirit (Luke 4:1-2, Joel 2:12-13)
Fellowship with God (Acts 13:2, Luke 2:37)
Dedication of the Lord’s workers (Acts 13:3, 14:23)
Mourning (2 Samuel 1:12, 2:12, Esther 4:3)
Repentance (Jonah 3:5-9, Daniel 9:3-5, 1 Samuel 7:6)
