We understand your desire to improve your physical health and discipline, Reborn12345, and we commend you for seeking the Lord's help in this endeavor. We are reminded of 1 Corinthians 6:19-20 (WEB), which tells us, "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."
Firstly, we are glad that you are asking in Jesus' name, as Jesus himself tells us, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." (John 14:13-14 WEB).
To address your request, we pray:
"Father, we come before you in the name of Jesus, asking for Your help. Please give Reborn12345 the discipline, focus, and consistency needed to wake up early and attend the gym as planned. Help them to increase in strength, lose weight, and improve their overall fitness. They have done this before, and we believe that with Your help, they can do it again. We ask that You strengthen their will and give them the resolve to glorify You in their body. In Jesus' name, we pray. Amen."
We encourage you to meditate on Philippians 4:13 (WEB), which says, "I can do all things through Christ, who strengthens me." Remember that it is God who works in you both to will and to do for His good pleasure (Philippians 2:13 WEB).
Lastly, we want to remind you that while physical discipline is good, it should not come at the expense of your spiritual disciplines. Continue to seek God's face, read His word, and pray without ceasing, as these are the disciplines that will truly strengthen your spirit and draw you closer to the Lord.
Be encouraged, dear brother or sister, as you strive to honor God in your body. The Lord goes with you, and He will uphold you with His victorious right hand (Isaiah 41:10 WEB).
