I moved away, far from home. I found a job right away, then was laid off right away. I was having trouble, worrying about life and keeping my finances in order. I was on the brink of sinking in a hole. I was in a real unstable position. A guy happened to hire me, I worked for a week and on Saturday night this guy called and wanted me to work the next day....Sunday. Not that I am legalistic about working on a Sunday, but I don't put God 2nd to work. I replied to him politely saying I will be going to church, he replied to me not so politely saying I dont have a job anymore. Already in an unstable position at the time, it was like the rug was ripped out from underneath me. I went to church the next day and God spoke. I wasnt paying all my attention to the message when Jerimiah 29:11 was put up on the sceen, NLT version. "I know my plans for you, declares the Lord, Plans to prosper you and not to harm you, plans to give you hope and a future." This is how I knew it was God. My ears shut out all sound, my knees went weak and my heart sank deep, deep down. I had to do all I could to hold back the tears. I felt so little and insignificant, yet entirely loved.
A week later a friend sent me a gift, a wallet, with that same verse engraved on it. Some other friends made me a calender a few weeks after that, Jerimiah 29:11 on the front. And of coarse, with no effort from me, God brought me another job just in the knick of time.
You can't really define how God speaks to a person, but when He does, you'll know it.
