“I looked for someone who might rebuild the wall of righteousness that guards the land. I searched for someone to stand in the gap in the wall so I wouldn’t have to destroy the land, but I found no one.” Ezekiel 22:30 NLT
God does not need anything from humans. He doesn’t need help with things, He doesn’t need praise from us; He doesn’t need our money in the offering plate.
He allows us to join Him as He brings about His plan.
But when the fullness of the time came, God sent forth His Son, born of a woman, born under the Law,
so that He might redeem those who were under the Law, that we might receive the adoption as sons. – Galatians 4:4-5 NASB
I don’t know any details of God that He hasn’t shared with everyone but I take the clause here “… in the fullness of the time ….” to apply to history.
Jesus was born when God, the Father, planned; not before, not after; His birth wasn’t hastened or postponed by anything.
