"Trust in the Lord with all your heart and lean not on your own understanding. In all your ways acknowledge Him and He will make your paths straight."
As you prepare for pregnancy and/or labor and childbirth, this verse should bring you comfort. God is in control of all things and He will guide you in all of it. Trust that God knows what He is doing in all of it, no matter how good or challenging things are. God is good and He is in control.
