balance b/w study and church ministry

This is the question/struggle I have been having since primary school days.

In primary school, I was struggling between music (piano, double bass, theory, music appreciation, etc), homework, and as a cell group leader.

In high school, I was struggling going to cell groups, youth service and preparing for the entrance exam to senior high school and university.

In university, I was struggling going to cell groups, preparing cell group teaching material, calling cell group members, prayer meeting of the cell groups, prayer meeting of cell group leaders, youth service, study, clubs, and basketball team and things I'd like to learn.

And gradually.....my views towards all these struggles gradually changed.
Now what I'm learning everyday is not JUST study, but the ministry that God has given me. Or I should put it in another way, study IS the ministry that God has given me, just as important as the ministry in the church. Therefore, of course I'd enocourage everyone to serve more in the church, to go to prayer meeting provided that they can manage other aspects of lives.

People always say "Honor God and He will honor you in what you do". However, I don't think this should be the reason to drag people to the "church ministry" and tell them that your grades will be fine because you've honored God. That's NOT true!
While giving out examples of this person still did lots of things in the church while preparing exams and God honor him at the end of giving him great results. Why not talk about people DIDN't get good grades because they are too busy
Here I'm NOT saying not to put God as the first priority but I believe that "church ministry" does not equal to "Honor God" nor "put God as first priority".
I study for God to become a better doctor because this precious opportunity was given from God!
Putting God first means study well for the exams, even if that means I can't go to prayer meeting, cell groups, practicing worship on Saturday.

Of course, there may be times where we do put "grades" above God and there may be time that God wants us to honor Him by serving in the church.

However, I simply want to say "please do not judge people who may need more time in their study. That doesn't mean that they don't honor God !"

Ideas, preferences, beliefs, habits, cultures, traditions DO NOT equal to the truth and principle that God has given us!

This is also a reminder for me till today.
