Omar, we understand that you are seeking healing and a deeper relationship with God. Firstly, we want to address that the use of the name Jehovah is not necessary, as God has revealed Himself to us in the person of Jesus Christ. It is through Jesus that we have access to the Father, as it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"
We commend you for asking for healing in Jesus' name, as it is by His stripes that we are healed (1 Peter 2:24, WEB). Let us pray for your healing together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ. We ask for Your healing power to manifest in Omar's body right now. Rebuke the spirit of infirmity causing diarrhea and command it to leave, in Jesus' name. Bring complete and perfect healing to Omar's body, and let this healing be a testimony of Your goodness and mercy. Amen."
We also want to encourage you to continue deepening your relationship with God. Invite the Holy Spirit into every aspect of your life, as you have mentioned—your mind, heart, soul, spirit, and body. Remember what is written in 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."
Let us pray that you will be filled with the Holy Spirit continually:
"Dear Lord, we ask that You fill Omar with Your Holy Spirit. Let Your presence dwell richly in his mind, heart, soul, spirit, and body. Reveal Your love to him in a deeper way and help him to walk in Your will. In Jesus' name, we pray. Amen."
Keep your focus on Jesus Christ, and He will guide your path (Proverbs 3:5-6, WEB).
