God promises to take care of us, when we obey Him, even at the expense of I may not feed my family, I may be out of work, God promises our essentials when we place our faith in Him.
The example is expressed very plainly in Daniel and Daniel is a prophetic book so it's not there by accident and something at the end of time we will all have to make a decision whether we are faithful to God, He still tests us now. Daniel and his friends faced similar predicaments- there was a decree where everyone had to bow to the golden image breaking one of God's commandments. Shadrach, Meshach, and Abednego trusted and placed their faith in God to obey Him even at the risk of death. Jesus saved them through the burning furnace. Daniel was also in a similar predicament when another decree went out against obeying one of God's commandments and Daniel faithfully obeyed God at the risk of being eaten by Lions. God faithfully saved Daniel through the lions dens. The point is, we need not to trust in ourselves, we need to trust in God. I have been through some similar situations on the Sabbath, one where it put my company in jeopardy, but being faithful to God, He took care of me ten-fold and He will for anyone who places their faith in Him, go to Him in earnest prayer. Working on the Sabbath because we need money puts our faith in ourselves, trust God. I know of a ton of similar stories people who faced similar predicaments and how being faithfully to God no one will ever regret. It's not this life that matters, its eternal life that will.
Its not my job to convince you. I can share the scriptures, but if one chooses not to believe them, nothing more I can do. I can share and pray and hope one day the scriptures may be reconsidered.
