We understand that you're seeking God's will and healing in your relationship. Firstly, let's address the use of the name Jehovah. The Bible tells us that salvation comes through faith in Jesus Christ, and it is by His name that we should pray Acts 4:12. Neither is there salvation in any other, for there is no other name under heaven given among men by which we must be saved.
You mentioned that you've been dating and praying to know Christ's perfect will. It's commendable that you're seeking God's will in your relationship. Let's pray and examine this situation according to God's word.
The Bible is clear about relationships, especially when it comes to marriage. The term 'dating' is not found in the Bible, but the principles of courtship with the intent of marriage are evident. A courtship should be God's will and honor God, a man and a woman with the intent of marriage Ephesians 5:31. For this cause a man will leave his father and mother, and will be joined to his wife. The two will become one flesh.
You mentioned that you've received guidance that you are not Christ's perfect and complete marital couple. It's important to accept this guidance with faith and obedience. God's will is always for our good, even when it's difficult to understand Romans 8:28. We know that all things work together for good for those who love God, to those who are called according to his purpose.
Regarding sentimentally healing, God is always willing to comfort and heal us. Psalm 147:3. He heals the broken in heart and binds up their wounds. Remember, God is close to the brokenhearted and saves those who are crushed in spirit Psalm 34:18. The LORD is near to those who have a broken heart, and saves those who have a crushed spirit.
Let's pray:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up these individuals seeking Your will and healing. We pray that You enter their minds, hearts, souls, spirits and bodies, revealing to them Your perfect plan. We ask for Your comfort and sentimental healing, trusting in Your promise to heal the brokenhearted.
Lord, we pray for their relationship. If it is Your will for them to be united in holy matrimony, we pray for a clear sign and guidance. If not, we ask that You give them the strength to accept Your will and move forward.
In Jesus name and by the power of His blood, we rebuke any spirit of disobedience, lust, or confusion that may be influencing their relationship. We pray that You help them to forget each other's love if it is not Your will for them.
Lastly, we pray for their spiritual growth. May they continue to seek Your face and grow in Your grace and knowledge.
In Jesus Christ's name, we pray. Amen.
