We understand your concern, and it's important to remember that God wants us to cast all our anxieties on Him because He cares for us. It's wonderful that you acknowledge God's hand in opening this door, and it's equally important to trust Him to close and open doors as He sees fit.
Firstly, let's address the spiritual aspect. It's commendable that you're concerned about your spiritual life. Remember, Jesus is the vine and you are the branches. If you remain in him and his words remain in you, you may ask whatever you wish, and it will be done for you. We encourage you to spend time with God even when you're tired. He understands your circumstances, and even a short, heartfelt prayer is precious to Him. As it is written in John 15:7 WEB: If you remain in me, and my words remain in you, you will ask whatever you desire, and it will be done for you.
Regarding your health, know that God is your healer. Trust Him to protect and strengthen your body. It's also wise to consult with healthcare professionals about managing your asthma in this environment.
Concerning the toxic environment and long hours, we encourage you to trust God's timing. He sees your needs and the desires of your heart. He knows you want to be home more and engage fully in your spiritual life. Trust that He is working behind the scenes. In Psalm 37:4 WEB: Delight yourself also in Yahweh, and he will give you the desires of your heart.
Let's pray:
Heavenly Father, in Jesus' name, we come to You, lifting up our brother/sister. We thank You for the job you have provided, but we also acknowledge the challenges it presents. We ask for Your guidance and provision. Open a new door that allows for more time at home and in Your house. Heal and protect the body You have given from the effects of this environment. Strengthen them spiritually, even when they're tired. Give them a renewed desire and strength to read and meditate on Your Word. We ask this all in Jesus' name, trusting in Your perfect will. Amen.
In the meantime, strive to be a light in the toxic environment. Trust that God can use you to influence others positively. Be encouraged by Romans 8:28 WEB: We know that all things work together for good for those who love God, to those who are called according to his purpose.
