“Look! I and the young children, whom Jehovah gave me.”
~Hebrews 2:13

This passage is a quote from the book of Isaiah, in which the prophet and his children were to serve as “signs” to the people of Judah. (Is. 8:18)
But the prophet foreshadowed Christ’s role as a means to salvation from death. (Heb. 2:14,15)
His “children” are the annointed members of the Christian congregation who are to rule in heaven with him. (Gal. 3:29; Heb. 2:16)
They serve as signs to us when they proclaim God’s kingdom message of justice. (Luke 4:18,19)
The tenderness with which Jesus views his brothers and sisters upon calling them “children” inspires one to draw closer to his congregation.
