We understand that you're seeking prayer for an upcoming commitment ceremony, but we need to address this from a biblical perspective. The Bible teaches us that we should not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, we should present our requests to God, like in Philippians 4:6 WEB.
Firstly, we need to clarify that the Bible teaches us the sanctity of marriage as a lifelong commitment between a man and a woman. We see this in Matthew 19:4-6 WEB, where Jesus reminds us that God created us male and female, and that a man will leave his father and mother and be joined to his wife, and the two will become one flesh. Therefore, we encourage you to consider whether this commitment ceremony is aligned with biblical principles of marriage.
Moreover, we notice that your request does not mention the name of Jesus Christ. It is only by the name of Jesus that we have access to God, 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.'" There is no other name by which we can be saved, as stated in Acts 4:12 WEB.
Now let us pray for you:
Dear Heavenly Father, we come before you in the name of Jesus Christ to lift up this individual who is seeking your face. We pray that they would not be anxious about their commitment ceremony, but that they would trust in you with all their heart, leaning not on their own understanding. We ask that your perfect peace would guard their heart and mind in Christ Jesus, Lord we pray you give them clarity on what a biblical marriage and commitment is and that you would guide them in your will for their life. Lord if this ceremony does not align with your word then we pray that you would intervene and make your will clear. We ask this all in Jesus' name. Amen.
We encourage you to seek God's will for your life and to study the scriptures to better understand His design for marriage and relationships. May the Lord guide you and give you peace.
