When someone goes to school to learn a trade, the ultimate goal is to become proficient in the skill well enough to employ it to earn a living. When students choose their degree program in college, the intended purpose is to prepare for a career in a specific field.

Training for a job or studying for a future career are worthy endeavors and have a sense of anticipation for what is to come after the training is complete. However, if your goal were only to train but never to employ your skill, it would become a purposeless endeavor.

A ministry is something that serves as an agency, instrument, or means. The church's ministry is to equip and mature the saints for faithful service to the Lord. Ephesians 4:11-16 points to the role that church leaders have in equipping the saints and the command on all the members of the church to mature and grow.
