“And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;”
1 Thessalonians 4:11
From scriptures, God appears to be somewhat indifferent about what work (legal and decent) we do in particular. However, He is definitely particular about us not being lazy.
Asides that, He is particular about us being able to fend for our families. See what 1 Timothy 5:8 says “But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel.”
He is also concerned about us remembering the poor (1 Timothy 6:16-17), as well as our giving to the spread of the gospel (2 Corinthians 9:1-8).
Whatever legal and decent approach you take with these guidelines in mind is fine with God.
What are you good at? What are the needs in your environment? What can empower you economically? Simple questions like these come in handy. “In all labour, there is profit…” (Proverbs 14:23).
It is your duty to be as effective as you can career-wise so that you won’t be distracted from your true purpose in life.
Can a Believer be led to follow a particular career path? Absolutely. However, if no specific leading comes, you need not sit idle. Where there is no specific leading, we must always take the most responsible step.
