1. About 90-95 of the world's leaves are green.
Leaf/greens symbolize' harvest, productivity, or fruitfulness. So, yes, you are right, your fruitiness/leaf has been tampered with, infiltrated by a threat or termites and it has polluted or stunted its growth or productively, a as result.
The mud/blue-black thing is the infiltration, the anti-growth, green-ness, and it is the one now spreading and hitting into the leaf.
What to do? It's not hard at all, you insist that God reveal the source of the termites, devouring agents on the leaf. For you to rise again, the mud/blue-black thing must be get rid of on the leaf.
Beg God to tell you to root and the source of that thing now if you don't want to be wandering and stay long in the wilderness as it's your first step to victory and quick recovery.
2. This is a mystery and I must confess, our God is indeed mysterious.
The Lord refers us here to the book of ;
◄ Psalm 121:1-2 ►
I lift up my eyes to the mountains— where does my help come from? My help will come from the Lord the maker of heaven and earth.
You see, I can see you are a woman of great faith whose faith and expectations are solely on God and that's good.
But what's happening to you, how can you lift your eyes unto the hill, to God almighty alone hoping for a change or a solution to a problem that's right before you, your reality yet pretending or acting like your problem does not exist or will go away as long as you maintain your gaze unto the hills? This shows that you have faith, know where his face is, and have access to God but wisdom is lacking in utilizing the privilege or grace to find a solution to your problem.
In a layman's language, the Lord says, you keep crying out to him, hoping, and looking unto him without coming to his presence with the right prayers, approach, or talking to him about your problem instead, you keep overlooking or pretending they don't exist as a way of faith for your problem to go away.
This is deep and mysterious indeed.
Bless
You.
