Prior to making a big decision or when we’re in a serious situation, it’s beneficial to fast and pray. Fasting allows us to have clarity to hear God’s voice.

It’s not a law to fast and pray before we make a big decision or when we’re in a serious situation, but throughout scripture we see people benefiting from its use. Moses, Elijah, Daniel, Paul, and Jesus, Himself, fasted so that they might draw closer to God (Exodus 34:28; 1 Kings 19:8; Daniel 9:3; Daniel 10:2-3; 2 Corinthians 11:27; Matthew 4:2).

We should let the Holy Spirit lead us on if we should fast or not. If He instructs us to fast, don’t fight it. Understand we’ll receive great clarity and our decisions will align with the will of God.

Then Esther sent this reply to Mordecai: “Go and gather together all the Jews of Susa and fast for me. Do not eat or drink for three days, night or day. My maids and I will do the same. And then, though it is against the law, I will go in to see the king. If I must die, I must die.”
Esther 4:15‭-‬16 NLT
