Not the weather.
In Matthew Chapter 16. verse 1. We find the Pharisees and the Sadducees asking Jesus for a sign from heaven
2. He answered and said to them, when it is the evening you say it will be fair weather for the sky is red.
3. And in the morning it will be foul weather today for the sky is red and threatening. Hypocrites!. You know how to discern the face of the sky, but you can not discern the signs of the times.
But that was all they knew, but we have an advantage over them. We have the Holy Spirit who teaches us all things in spirit and in truth. We can ask him about something we are not sure about and he will give us an answer. We can then discern which way we should walk with him.
Verse 20. Now unto him that is able to do exceeding, abundantly above all that we ask or think according to the power that works in us.
Have a good look at this verse God is able to do much more than we can think or ask, Look at these words exceeding, abundantly they mean what they say, no limit providing we are asking in line with the will of God This is the key to all our prayers they must be in line with the word of God. Then into this verse comes more than we can think and that is according to the power that is within us. That is the Holy Spirit who is part of the Trinity that lives within us. I do not think we have called on that power in the abundance described here.
In modern day language God is saying to us, think big there is nothing that is impossible to me
