Realizing God is your provider and not yourself or your job is liberating. If you honor God, he will honor you. I keep the 7 biblical feasts established by God that are found in Leviticus 23 along with the 7th day (Saturday) sabbath. I told my current employer I will not work Saturdays and there are high holy days I would not be working. I straight up told my boss that God is my provider and not him and if I honor God he will honor me. He was kind of taken back by it but it hasnt been an issue.
