(Psalm 119:49)
God, unlike us, doesn’t idly reminisce. The essence of God’s ‘remembering’ lies in His acting toward someone because of a previous commitment.
When He ‘remembered’ Noah, or His covenant with Abraham, this human term meant that His time was now ripe for action.
(B. S. Childs)
"Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and you will call him Immanuel."
Isaiah 7: 14
