God didn't say labour to fulfil d promise but to enter into the place of rest. Rest is a place of full persuasion. It is when your heart completely agrees with the words you are speaking in faith declaring the promise which was once considered impossible as your present reality.
It is because of God's mercy we are not consumed. When in trouble rely on the mercy of God. Lift your eyes to the hills from there comes your help. Look not to the arm of the flesh, trust not in riches. God's eyes roam the earth to find that man who will hope only on His mercy.
The way you know the character of an organization is not how they treat people that join the organization, you know the character of an organization by how they treat people that leave the organization.
