Jeremiah 31:17

And there is hope in thine end, saith the LORD, that thy children shall come again to their own border.

In its original setting the promise gives sure hope to exiled Israel of restoration after the Babylonian captivity, that their children will return to their homeland. It was spoken to weeping mothers in Israel and belongs to faithful parents in present bereavement over their children. That includes the mothers of Bethlehem, to whom comfort is given by the promise that their children will come back from the land of the enemy.

The land of the enemy means death, and coming again to their own border means resurrection and reunion, with children returning from death to their parents. The promise applies to parents whose children have died, that he will restore those children to them. Faithful work for children shall be rewarded, so weeping should cease, because hope remains in the end that children gone into the land of the enemy shall come again to their own border. That reward belongs to faithful parents who have labored for the moral and religious training of a child, whose dead son and brother, now safely beyond anxiety in the tomb, shall come again.

The promised return will occur when Christ returns and the dead are raised. It is a soon-coming reunion that will be eternal and a joyful resurrection to the life to come, to life, glory, honor, and immortality just beyond the tomb. Even in seeming severity the Lord upholds while He smites, giving mourners comfort and calm assurance of faith pointing beyond the tomb to bright scenes just beyond. That restoration brings comfort beyond present grief, for children lost through death will be restored to their parents. Bereaved parents have hope that their children will return from death and be reunited with them, seeing and knowing them again in the heavenly courts. In vision that return is connected with an innumerable company of little ones among the redeemed.
