A Profession or A Call?

Excerpt from K. P. Yohannan's book Against the Wind:

But there is a definite difference between a profession and a call: 

A job, a profession, is one you choose; a ministry is one Christ chooses for you.
A job depends on your abilities; a ministry depends on your availability to God.
In a job you expect to receive something—a salary; in a ministry you expect to give.
A job well done brings you self-esteem; a ministry well done brings honor to Jesus Christ.
In a job you give something to get something; in a ministry you return something that has already been given to you.
A job well done has a temporal reward; a ministry well done has eternal rewards. (Author unknown) 

I want to ask you: Are you called? Have you heard the Lord Jesus call you, saying, “Come, follow Me, be with Me and I will send you out for ministry”? The person you become, the decisions you make, the manner in which you behave and your attitude toward the Lord’s work all depend on this deep conviction that you have been called by God.
