“Although I have removed them far away among the nations […], for a little while I will become a sanctuary for them in the lands to which they have gone.”
Even when Jehovah God decides to discipline someone, he does not abandon them.
Jehovah wants those he disciplines to learn to rely on him.
The Jews in Ezekiel’s time were being taken captive to Babylon. (2 Ki. 24:14,15)
Those remaining ended up fleeing to other nations. (2 Ki. 25:26)
Regardless of where they ended up, Jehovah was still reaching out individually to those who wanted to worship him.
Nowadays, for whatever reason, someone might find him or herself separated from the congregation.
Jehovah wants to comfort any of those who call out to him in prayer, as he will never desert those who actively seek him. (Neh. 9:31)
