To enjoy and love children both partners need to be truly prepared and fully in love with each other - that both only is possible with the right partner.
A relationship with a wrong partner often leads to the attempt to enjoy sex while avoiding pregnancy by birth-control or prevention of pregnancy by any means. A true love relationship is like an ocean - in an ocean there is room, food, space, fun and more for billions of living creatures - so is the ocean of love a man creates for his divine wife sufficient for any number of angel children. God alone guides the number and time of pregnancy because finally it is God who cares for all, feeds all by letting billions of tons of food grow and by giving you all a most beautiful planet earth until you return home to heavenly paradise after having successfully completed all lessons of love here and now on earth.
