Sleepy, if I were you and you're still not sure, why don't you apply for it anyway and ask God to show you if it's for you. Getting the application form will not do any harm, and will give you more time to seek God on this. Sometimes we don't get a clear answer right away. You don't even have to send the form in if you feel it's not what God wants.
Thank you. I decided to begin my application but feel too tired to concentrate and give it my best because I had to ring around for my 3 referees and they could 'talk for England' therefore the clock is now too much against me and I need some rest tonight. Maybe God does work in mysterious ways as I had some cracking conversations tonight though no application. I hope there's another opportunity around the corner.
