"Then the LORD said to Moses, “See, I have chosen Bezalel son of Uri, the son of Hur, of the tribe of Judah, and I have filled him with the Spirit of God, with wisdom, with understanding, with knowledge and with all kinds of skills— to make artistic designs for work in gold, silver and bronze, to cut and set stones, to work in wood, and to engage in all kinds of crafts." Exodus 31:1-5
Some people have the idea that a person must be a vocational minister in order to really serve God on some elevated level. This thought couldn't be further from the truth. While God does call some people to be vocational ministers, He also calls people to a vast array of other professions and equips them for those things.
Bezalel had the hand of God upon him and was given all kinds of knowledge, creativity, and craftsman oriented skills which could be used for His glory. God has similarly given each person unique abilities and empowered them to serve Him through those skills.
If you're a good teacher, do that as unto Him. If you're good at construction, do that as unto Him. If you're gifted with financial matters, serve Him in that arena. If you're artistically inclined, let Him guide your creative efforts.
No matter what your job is, do it well and in a way that would glorify God. This can open doors to share with co-workers, clients, or vendors about spiritual matters. You may be the first person they've encountered who demonstrates Jesus in real life outside the walls of a church building. Many people give up on church or have just never had interest in going but would be open to listen to someone they respect in the professional world.
We are all vocational ministers. Some have the title of pastor while others have the title of accountant, nurse, salesman, police officer, waitress, or custodian. God has given you talents and abilities, use them to bring glory to Him.
