Make this valley full of ditches. For this is what the Lord says: You will neither see wind nor rain, yet this valley will be filled with water (2 Kings 3:16b, 17a NIV).
God performs miracles only where there is expectation. Even when the need is pressing, many fail to expect God to do something though they pray. The three kings in this incident and all their troops and animals ran out of water as they marched out to attack Moab.
As they approached Elisha the man of God for counsel, they were told to have expectation of a miracle. In the same way, when you are in a desperate situation in life, expect God to work in that situation when you pray. Expectation is the real key on which faith operates.
Not only should you have expectation, but this expectation should be acted out. As someone said: “When you pray for rain, carry an umbrella!” In the case of these three kings they were asked to make the valley full of ditches to collect the water they were expecting to receive.
Now acting that out required faith. But unless they expected water to come they would not have been able to dig. So taking some kind of action which shows your expectation is very crucial if you should be able to receive a miracle.
Another thing to be noted is that the miracle may not come through expected channels. When the need is overwhelming, God at times answers expectant faith through unexpected means.
Here they were told that they will neither see wind nor rain. But they received water.
Likewise, when you expect and act in accordance to your expectation, God meets your need and also adds something more to the miracle as He used this miracle as a means to defeat the Moabites.
