I've always hung onto Phillipians 4:13, "I can do all things through Him who strengthens me." (NASB). Although I do like other translations better, you do get the general idea.
I also love Jeremiah 29:11 "For I know the plans that I have for you, declares the Lord, plans for your welfare and not for calamity to give you a future and a hope." Again, I do like other translations better, but this is the Bible that was closest to the computer at the moment.
You know they say in nursing to have flash cards ready to study.But I think it'd be awesome of you'd put some great Bible verses in the pile to remind you of the Lord's presence though all of nursiing school.
You'll have my prayers, and the very best wishes to you!
