We're messing around too much with God's nature.
I would agree to this point, we are messing around with HIS plan. People think that they can have their own plan by having non consequential sex for years, then in a blink of an eye, get off birth control and have babies in their late 30's. Then when they don't get pregnant after one month, they rush to the fertility doctor because "their" plan isn't working and their biological clock is running out. I'm not passing judgement on people and I in no means imply that GOD punishes these people with autism because GOD does not work this way, we know there are aways travails in life and all children are a sacred gift. We also know GOD is a forgiving GOD and many who have turn to GOD later in life are recipients of his GRACE no matter what. What is does tell us that man's wisdom alway seems to fail when compared to GOD's plan. This is true for the believer and non believer alike.
