What does the Bible say about fasting in Christianity?

The Bible does mention fasting, but it often speaks against the ritualistic nature that some have imposed upon it. Matthew 9:14-15 reveals that Jesus' disciples did not fast while He was present, as His company was a time of joy, not mourning. Ritual fasting, as practiced by the Pharisees, was merely a tradition that did not align with God's purpose. Fasting should come from a heart that seeks communion with God rather than as a means to display superficial religious stature. True fasting is rooted in understanding our relationship with Christ, who is our joy and sustenance.
