Should we use prudence and wisdom to make our lives go smoothly?
I think we should, as long as we accept any tribulations or setbacks from God with a generous heart.
But we shouldn't do anything to BRING disaster upon ourselves (investing our life savings in the stock market, sending our children to public school, having a TV in the house, buying your pre-teen a cell phone, or marrying the wrong person)
Besides, if WE choose to do something ("I don't care if we're from two different worlds. I want to marry him!") then it's on US to deal with the consequences. It wasn't God's will, only His permissive will.
We can make our salvation much more difficult because of OUR OWN CHOICES.
Matthew
