Very glad to see your message. I was in Chennai for a while, now I am in Bangalore. I too have a secular job. I understand what you mean when you say you felt like prisoner of circumstances.
I am glad that you are teaching your church youth. That is a great way to start.
I hope that you keep at it, till God shows you the direction. I have often seen in the life of great servants of God that they started small. They were faithful in the little which God showed them and then God said, “well done, good and faithful servant” and more responsibilities followed.
Regarding your secular job, I am reminded of a sentence mentioned by a friend. He said, he shifts from a secular job to another when he has shared gospel with more than 80% of his colleagues. That is a good way to make sense of the job that God has laid on us.
There are several ministries waiting for people to help them during spare time. If you are interested in teaching kids, you probably should see if COME ministries is requiring anyone to go to the slums nearby to help.
