This question is a wow.
We know how capable God is in all situations as he stated in the holy. When he made it clear that we should cast all our burden to him and he shall give us rest.
His capability is even beyond our problems, how do you expect me to start asking just one thing from who I know will be able to solve all.
As a typical Nigerian man will say "Wahala no dey finish" which means problems don't end they come in batches. You solve one and another comes up far beyond the one solved.
In a case like this, all one needs to do is sit and think of a problem that when resolved other problems will have no option but to also go with it, even though it's impossible to do away with every problem in life but at least one should be able to make a wise decision in this case.
What is the one thing I will ask from God?
This is a bit difficult but the decision had to be made.
Just like King Solomon in the bible who made just a request and all other things were added to him his request was based on the position he was handling at that time. He asked for wisdom and God said because he asked for this he will add all other things to him.
Again there is something God himself mentioned in his holy book (Bible) When Christ was teaching his disciples about the kingdom of God he made it clear that there is only one thing you will ask and all other things shall be added unto you.
Matthew 6:33"Seek ye first the kingdom of God and all other things shall be added unto you" mind you he did not say somethings will be added but "EVERYTHING"
So, if I will ask, I will say God should grant to me his kingdom.
What is the response I will need from God?
This "B" part of the question is a straight question that everyone will give a straight answer to without complaining if the request is given then what the response should be shouldn't be any problem.
As everyone will require a positive answer to whatever request one makes.
And that positive answer I will expect is just granting to me that request which I asked from him just like he granted to so many other people in the holy book example of such people is Solomon when he asked for wisdom, Samson when he asked for strength, Hannah when she asked for a child and so many that I can not mention at the moment.
And all these peoples' requests were met just as requested from God.
I won't say more than this so as not to mess things up thanks for going through this.
And also most appreciative to the #ecotrain community for this wonderful engagement.
