When Yahweh does something it is at the right time.

"But when the fullness of the time came, God sent forth His Son,..." Galatians 4:4

When Yahweh gives it is always just the right thing to meet a need.

" ..., God sent forth His Son,..." Galatians 4:4

When Yahweh picks someone it is always the right person.

“….born of a woman,….”Galatians 4:4
