One reason often given for justifying the use of birth control is that the couple could not possibly handle another child. But how silly is this attempted justification when we examine a few simple facts.
God is the author of all life, and as such He alone determines when to bless a couple with a child. He is an infinitely good, wise, and loving Father to His poor children, and He would (could) never give us anything that was not for our own betterment. No matter how much we may disagree with His plan, it is always for our own good.
This means that when a couple really could not possibly handle another child, God will not give them another child. There is absolutely no need to use any form of birth control. If a couple mistakenly believes that they could not possibly handle another child, and God determines otherwise, what does the couple have to fear? They should humbly understand that their Heavenly Father is sending them another child because it will bring them closer to Him. The lucky couple should thank God for the gift, and bless Him for His wisdom.
It seems that the fear of raising children comes from two sources–an unfounded trust in ourselves, and a lack of confidence in God. These two ills can very quickly be remedied by simply embracing the truth. We are but poor and miserable creatures capable of absolutely nothing on our own, while God is infinite perfection and power.
Believe this, distrust ourselves, have confidence in God, and any fear of raising children will evaporate. Oh, and so will any supposed need for birth control.
