The only thing that is scary about it is knowing that God has a plan for us all and whether or not we will be able to follow through with it. Not having a personal relationship with God would make it impossible to please Him. The comforting point is that He does have a marvelous plan for our lives and if we trust Him and Believe that He knows best, and depend on Him--His plans for us will be successful... I believe Paul brought it up to let the Ephesians know that there is a plan for our lives - already predestined - if we choose to follow it. Praises were given to God because it let the Ephesians know about the plan and that they could fulfill it via obedience...
