We understand your urgency and desire to seek God's favor in your marriage. It's wonderful that you're turning to God to strengthen your bond. However, we must address a few points to align your request with biblical principles.
Firstly, it's important to understand that God's favor is not merely for our personal gain or to control others, but for His will to be done in our lives. True love is patient, kind, and not envying and does not seek its own way. The description of love is found in 1 Corinthians 13:4-8 WEB:
Love is patient and is kind. Love doesn’t envy. Love doesn’t brag, is not proud, doesn’t behave itself inappropriately, doesn’t seek its own way, is not provoked, takes no account of evil; doesn’t rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things. Love never fails.
Instead of asking God to control your husband's feelings or actions, pray that God helps you both to love each other as He loves us. This includes respecting your husband's free will and allowing him to make his own choices, trusting that God is working in his heart. We should be casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ, (2 Corinthians 10:5).
Secondly, it's crucial to understand that prayer is not about using specific formulas or phrases to get what we want. It's about communicating with God and aligning our will with His. There's no need to repeat phrases or use specific words to ensure your prayer is heard. God looks at the heart, not the repetition of words, Matthew 6:7 WEB, "In praying, don’t use vain repetitions, as the Gentiles do; for they think that they will be heard for their much speaking."
Lastly, you mentioned the name of Jesus Christ, which is wonderful. It is in the name of Jesus that we have access to God 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."
Let's pray together:
Heavenly Father, we come before You in the name of Jesus Christ, lifting up this beloved sister and her husband. We pray for Your will to be done in their lives and marriage. Help them to love each other as You love us, with patience, kindness, and selflessness. Grant them wisdom and understanding to navigate their relationship in a way that honors You. Protect their marriage from any attacks of the enemy and draw them closer to You and to each other. In Jesus Christ's name, we pray. Amen.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
