God laid a stone in Zion, Isaiah says, a tested and precious cornerstone, and whoever relies on it will never be dismayed. Paul tells you what the building became: a family, where you are no longer a slave but a child, and an heir.

The difference between servants and sons is not the work they do. It is the reason they do it. Today sorts that out in you.

Judah's rulers signed what they thought was insurance, a covenant with death, and God countered with masonry: a tested cornerstone, load-bearing and immovable. Every generation repeats the choice, clever arrangements versus one reliable stone.

Galatians names what the stone built: a household. The set time fully came, the Son was sent, and the Spirit now teaches your heart its native word, Abba. Slaves calculate; children rest. Whatever you do for God this week, check the engine underneath it. Fear produces employees. Adoption produces family resemblance, and the resemblance grows on its own.
