Proverbs 21:1 The king's heart is in the hand of the Lord. As the river of water he turns it whithersoever he will.
[2] Wherever possible, ask if a substitute could fill in for you, or if possible, if you could make up your hours on another day. There are times when someone might be willing to substitute for you, so that you can have the Sabbath day off to worship God. Pray about it, and ask those who are in charge. It may be that they would let you off the hook, or that some other arrangements will be made to accommodate you.
Remember that God looks at your intentions and at your heart, so that if it is sincerely in your mind to serve God, He might just send you a Cherub to turn things in your favor. [3] To those who are directly involved in saving life, such as doctors, nurses and everything in between. If your purpose is to serve God in sincerity and truth as the fourth commandments says, you should do everything possible to minimize unnecessary work.
The reason for this is so that your mind can be stayed on The Lord, even as you attend to the sick and the suffering. As is clearly stated by the prophet of God, the sick are to be cared for at all times, but over the Sabbath great care should be taken to avoid conversations, and work that isn’t directly tied to the saving of life or the healing of the sick. If the heart is right, the actions will follow suit.
Isaiah 26:3 Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
May God add His blessing to the study of His word. “Good night” and God bless!
