“What is a personal calling?
It is God's blessing, it is the path that God chose for you here on Earth. Whenever we do something that fills us with enthusiasm, we are following our legend.
What is your personal calling?
We all need to live a life worthy of the calling we have received (Ephesians 4:1).
Rom. 8:28 We are assured and know that [God being a partner in their labor] all things work together and are [fitting into a plan] for good to and for those who love God and are called according to [His] design and purpose.
Our purpose in life is the very meaning of our existence and without knowing this we often suffer ignorant of our own significance. ... The Bible offers many insights into man's purpose on Earth and living within a meaningful mission. For we are God’s handiwork, created in Christ ...
For consider your calling, brothers: not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth.
But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong.
We must work the work of Him that called us.
