We understand your struggle and desire to lose weight, especially with the motivation of a new job. However, it's important to approach this situation with a biblical perspective and ensure that our priorities are in order.
Firstly, we should recognize that our bodies are temples of the Holy Spirit, and we ought to honor God with our bodies. This means taking care of ourselves physically, but also remembering that our worth is not determined by our outward appearance, but by our hearts and our relationship with Jesus Christ.
1 Corinthians 6:19-20 WEB: "Or don’t you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God’s."
While it's commendable that you're trying to control your eating habits, we encourage you to do so in a healthy manner. Fasting and praying can be a powerful spiritual discipline, but it should not be used as a mere means to lose weight.
Instead pray:
"Dear Lord Jesus, help me to honor my body as a temple of the Holy Spirit. Give me the strength to make healthy choices and the discipline to take care of myself physically. Help me to keep my focus on you and not on the fleeting standards of the world. Help me to do my best in my new job not based on how I look but how I perform. Guide me with your wisdom for my body and life. In Jesus' name, we pray. Amen."
Lastly, remember that God looks at the heart, and that is what truly matters.
1 Samuel 16:7 WEB: "But Yahweh said to Samuel, 'Don’t look on his face, or on the height of his stature, because I have rejected him; for I see not as man sees, for man looks at the outward appearance, but Yahweh looks at the heart.'"
We encourage you to pursue health and fitness in a balanced way, keeping your focus on Jesus and on being conformed to His image, not the world's.
