This passage is an example of how fasting can be a form of worship to God. Restricting ourselves from a certain thing can give us more time to worship and glorify Christ.

Also, this chapter in Acts shows how when we take time to fast that God can speak to us. The fasting gave the clarity and quiet for the Holy Spirit to speak to them and tell them that he has set Barnabas and Saul apart for specific kingdom work.

This encourages us to practice fasting as a way to allow for God to be able to tell us what He is calling us to do. Fasting can open our ears to hear the desires and purposes that God has prepared for us.
