Isaiah 43: 18
But forget all that - it is nothing compared to what I'm going to do.
God did not forget his people, even though they were in captivity. He planned to give them a new beginning with a new purpose - to turn them into a new people. In times of dire circumstances. it may appear as God has forgotten you. But God may be preparing you, as He did the people of Judah, for a new beginning with Him at the center.
He knows the future, and his plans for us are good and full of hope. This does not mean that we will be spared pain, suffering, or hardship, but that God will see us through to a glorious conclusion.
