What does it mean to hope and have faith?

I wish I knew the answer......
I have been praying desperately that the other woman would not be carrying my husband's child. I have also been praying for strength to accept His will. In reading about the Little Flower, they say that she had so much confidence in God: a childlike confidence that is very pleasing to Him.

So, do I believe that God will grant my request with a childlike simplicity, or would that be arrogance? Would God prefer me to just pray to be open to His will? Or, would me doubting that God will grant my request not be having the faith God asks of me?

I am so torn. I don't want there to be a baby. I also want strength to deal with it if there is. How can I pray for both? How do I petition God without being arrogant or doubtful?

Dear Lord,
I believe that you can see the big picture and know that you will give me strength to face the future. Please do not scorn me for being frightened and confused. You understand my motives, my fears, and my desires. Grant my request, I humbly ask, Dear Lord, or give me strength to face your decision. I know that my fears are silly, because whatis there to dread when I know you're in control? I keep begging for that cross to be taken away, but know that you can only know what is best. Please do not make the punishment for this sin be so severe, especially since it would hurt the innocent most: the child, my child, and myself, though I know that my soul is not free from sin. Have mercy on me for my sins, on my husband for his weakness, and on her for her cunning and intent to steal what belonged to me.
In your Son's Name, I humbly pray.
