Just When I Think I have my emotions under control...

Tonight, during our Marraige on the Rock class, we were discussing money. This is CLEARLY an area in which we have lots of room for improvement. HOWEVER - We have worked really hard to get to where we are. All of that to say that my greatest fear in making a decisions about IVF or Adoption is that we won't be able to pay for it. IVF costs about 14000. There is no payment plan- you just write them a big fat check the day of the procedures. AND the chance that it will work is a whopping 45%. WOW. International Adoption (the only kind we will consider) is 30000. It can take up to 6 years at the most.
We have considered and prayed. The pros for IVF is that we can actually have a child that has our genetic structure. How amazing. The con is that, there is a 55% chance that it will NOT WORK. How very devastating. Pros for International adoption - We get to give a child a future that they would never be able to have without us. Cons- Let's be honest...The kid could be crazy, have some insane medical problems that weren't detected, AND IT COSTS 30000. How is the world would be pay for that? YET tonight I heard the most amazing story from a woman who is oblivious to my situation. She was unable to get pregnant and decided to pursue adoption. After exploring all of her options, she and her husband through much prayer, decided that they would adopt a little boy from Korea. At that time the cost was 20000. They had 200 in their savings. Over nine months, God miraculously provided 18700 to them. They said they had no idea how that happened. The week that they got their son, their finances somehow returned to normal. WOW. God provides. I know that he does.
Chad and I have prayed and prayed and prayed. I have felt little to no confirmation about one choice or the other. Chad has felt a heavy pull toward adoption. Now I just pray constantly for God to give me some answer....some feeling...so that I know that we are making choices that are in the center of his will. Was hearing this story a coincidence tonight? Or was it God speaking through one of his people to tell us that he will provide? How do I know?
