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 4:16 NLT

Fasting is most often a tool for praying specifically with laser-like intention and focus on one topic – an important decision, a stronghold of sin, or even a national crisis like the one Esther was facing. Pray and ask God to point his laser beam into your life and show you where you may need a focused time of prayer or fasting. Write that in the center of the page and draw a shape around it. From that central idea, brainstorm actions you need to take and draw the thoughts God brings to you as an idea map.
