Genesis 30:22 contains a phrase that deserves examination: "And God remembered Rachel." The Hebrew zakar — "remembered" — does not imply God had forgotten her. In the Old Testament, when God "remembers" someone, it means he is moving into active involvement on a prior commitment. Rachel had been waiting — watching her sister bear child after child — for years. The "remembering" is the end of the interval, not the end of God's attention during it. The interval was not abandonment.
Psalm 139:13 says God "covered me in my mother's womb" — the Hebrew word qanah means to acquire, to own, to create with care and ownership. The creative act in the womb is described as God's own work, his own crafting. IVF involves medical assistance in a process God calls his own. Using medical help to assist that process is not stepping outside God's domain — it is using the knowledge he gave to medical science to cooperate with the creation he does.
