Whenever God begins something, we have the assurance that He will finish it. Nothing will stand in the way of Him accomplishing His purpose in this world and in our lives. What God starts, He finishes, and nobody can hinder Him. Sure, delays will happen. Just remember, God is in charge of the delays as well as the progress.
One atom in this universe cannot move without dragging the whole world along with it. There cannot be any progress without the whole world following in the wake, and it is becoming every day dearer that the solution of any problem can never be attained on racial, or national, or narrow grounds.
