But I have stilled and quieted my soul; like a weaned child with its mother, like a weaned child is my soul within me
We have to rest in the LORD and not get restless like the Devil who goes to and fro looking whom he may devour. Restlessness of the soul (mind) has it's origins from the sinful nature of the Devil in you. The Devil is a restless being and if you keep obeying the sinful nature of the Devil in you, you too will eventually mature into being a restless being. Always up to some kind of mischief all the time like the Devil. You can't keep still for a moment. You are always committing some kind of sin in your life. Your thoughts and ways are always contemplating evil. You can't keep still. You can't remain quiet. You get very restless. You can't make up your mind. Your mind gets restless. You 'll start looking here and there for help. Your trust isn't in the LORD. Your trust is in another flesh. One day, you trust in this man and on another day, you start trusting in another man. You are being driven by your restlessness, here and there. Like you are being tossed by the wind, here and there. You are not trusting in the LORD. You are trusting in men, in another flesh. If you can't trust in the LORD quietly, like a child is being weaned by it's mother, then say so. Don't confuse others by saying you are trusting in the LORD. You are not!
This is what the LORD says: "Cursed is the one who trusts in man, who depends on flesh for his strength and whose heart turns away from the LORD. He will be like a bush in the wastelands; he will not see prosperity when it comes. He will dwell in the parched places of the desert, in a salt land where no one lives. "But blessed is the man who trusts in the LORD, whose confidence is in him. He will be like a tree planted by the water that sends out its roots by the stream. It does not fear when heat comes; its leaves are always green. It has no worries in a year of drought and never fails to bear fruit."
