Ecclesiastes 3:11 says " He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end". The Lord is not the one not to keep his promise, God is the promise keeper and the way maker, God who delivered the Israelites from the hand of the Egyptians will deliver you from very trouble, persecution and problems you're passing through. The Bible says this vision is yet for an appointed time though it tarries wait for it. Wait for God's appointed time and do not be in a hurry for success so you won't miss your divine timing.
