Biblical Answer

Jesus teaches that Christians should fast, but he does not say how often or for how long. In fact, he says that the disciples will fast when he is taken away from them, which refers to the cross (Matthew 9:15). Jesus assumes that his disciples will continue to practice voluntary fasting, but he does not provide specific instructions. He emphasizes the value of fasting as a sign of repentance before God rather than as an effort to impress others with personal piety.

Jesus' teaching on fasting is rooted in the Old Testament, where fasting was a way to humble oneself before God and seek his presence. Moses fasted when he received the Ten Commandments, and Jesus fasted forty days as he prepared for his earthly ministry. Fasting is a way to pray with our bodies and offer all aspects of our lives to God. It is not just about giving up food, but about seeking God's presence and guidance.

The secret to fasting is not giving up food, but spending time in the presence of God. Fasting is a powerful spiritual discipline that can help us grow closer to God and become more like him. It requires self-control and discipline, but the rewards are well worth it. As Jesus said, "The days will come, when the bridegroom is taken away from them, and then they will fast" (Matthew 9:15). This refers to the time when Jesus is taken away from us until the day he returns, and it is a reminder that fasting will become a spiritual discipline again in the future.
