Nice to see another Brit(?)
First off, I really relate to your situation. While I’ve done my A-levels and am about to finish my uni degree, I’m also at a crossroads on where to go from here.
Some food for thought: sometimes, I can trust my instinct and how I feel about something. Sometimes, I can’t. I often FEEL like I want to do something sinful, and in these moments, I have to trust God to do for me what I cannot do for myself and relieve from me insanity, regardless of how I feel. Sometimes, my feelings are very useful, like when my friends ask me to go out drinking heavily and partying with them at a nightclub: my feelings warn me that that’s probably not what God would have me do (I come from a family of alcoholics,) and I trust that the slight unsettling feeling in my stomach is a sign that I shouldn’t go. The point is: how YOU feel about something may not be the acid test for whether not it is what God would have you do.
There is no easy answer, and there shouldn’t be: this is important. What I would say is, pray for usefulness to God - humbly ask Him how you can best serve Him. For myself, I ask, and say, ‘God, please help me think not only how I might benefit from this decision, but how I might best serve You, and be useful to other people through serving You.’ And then, you have to take a step back - and sometimes pay attention to the little things. I think this passage, called Watch and Listen, says it well.
"Watch and listen carefully.
The man whispered, “God, speak to me” and a meadowlark sang. But, the man did not hear. So the man yelled, “God, speak to me!” And the thunder rolled across the sky. But, the man did not listen.
The man looked around and said, “God let me see you.” And a star shined brightly. But the man did not notice.
And, the man shouted, “God show me a miracle!” And, a life was born. But, the man did not know.
So, the man cried out in despair, “Touch me God, and let me know you are here!” Whereupon, God reached down and touched the man. But, the man brushed the butterfly away and walked on.
Don’t miss out on a blessing because because it isn’t packaged the way that you expect."
Just to add here - I chose chemistry and physics, and I loved them! But then, if I chose again now, I’m sure I’d be more drawn to theology now. funny how life works like that!
May God bless you!
