Religious people often think humility is their way to accept the Lord into their hearts. However, it is human nature to improve their quality of life. But it's important to keep our hearts under control and always track what place money and possessions take in our lives. As money can easily become an idol, you need to determine what your real motivation is and understand self-realization in a Christian way.
What does it mean? The main question is: what do people consider the meaning of their financial realization? Traditionally, self-realization is understood as the disclosure and realization of one's abilities and everything that is given to you. But the goals are different for everyone. For some, it is glory, power, honor, and wealth. And what should be the goal of a religious person? From the church's point of view, a person should realize himself - no matter what they do - through any of their actions, deeds, and relationships with other people, including at work. The main thing is that your activities correspond to the ideas of Christian morality.
For example, can a Christian want to become a leader? Maybe, if they feel a calling in themselves and a resource to do something good in this post. If you know how to implement a project, take a leadership position and do your part to create something good. Motivation is important here: not power in itself, but bringing benefits and creating good. Getting paid for your work is fine. But it is important to strive not for financial heights but for quality heights, a tangible result that benefits others. That's the point.
