Something I haven't shared here before: My DH prayed for twins about a year before we found out. He teaches at a Christian school and prays before the beginning of his homeroom with his class. During the prayer he said he felt a very strong instruction from God to pray for twins. And he thought, why that's silly. But towards the end of the prayer he still felt that God was telling him to pray for twins. So he added to the end of the prayer, "and so thank you for my two children, and if you choose to bless me with twins in the future, so be it."
Then he forgot about it.
Exactly a year later, I call him to tell him it's twins, and he's with the SAME CLASS. I rarely call him during school but of course he had to know. He got off the phone with me, told the class, and one of the girls said, "But Mr D, you shouldn't be so surprised, we remember you praying for twins."
So my DH uses that as an example of how God puts desires in our hearts of what He wants for us and all we have to do is ask.
What did I say when he told me about the prayer a year later?
"You should have asked me first"
