‘Plans to give you hope and a future’ means that God will reward His children with the desires of their hearts as they prepare for the future. God reminded the Jews that their situation is not permanent and that they can continue to rest in His promises as He is still in charge of their personal lives.Even though they are held captive, God’s mercies never fail and they are to expect God to fulfill His divine purpose in their lives.While the situations may not be ideal at this time for the Jews as they are under Babylonian rule, God has not forgotten about them.There was no immediate plan to end their suffering but in His great plan, His purpose is to give them a future that will allow them to restore their faith in Him and reap the rewards of His tremendous blessings.
