We understand that you are in a complex situation and we are here to pray with you and provide biblical guidance. Firstly, we commend your faith and hope in God's grace to change the father of your child. It is clear that you have a heart for him and your family. However, we must address certain elements of your situation that are not aligned with biblical principles.
Firstly, it is important to understand that having a child outside of marriage is not God's design. The Bible teaches us to flee from sexual immorality and that our bodies are temples of the Holy Spirit 1 Corinthians 6:18-19 WEB. It is never too late to repent and ask God for forgiveness. His mercy and grace are sufficient for us.
Secondly, the fact that he is involved in drugs and gambling is a serious concern. These activities are not only harmful to him but also to you and your child. The Bible tells us to be sober-minded and watchful, for our adversary the devil prowls around like a roaring lion, seeking someone to devour 1 Peter 5:8 WEB. It is crucial that he seeks help and turns away from these destructive behaviors.
Thirdly, you mentioned that you have talked about marriage before, but it is unclear if there is a commitment to marry in the future. Marriage is a lifelong commitment between a man and a woman, and it is a covenant made before God. God hates divorce Malachi 2:16 WEB, so it is important to enter into marriage with a sober mind and a wholehearted commitment.
You also mentioned that you are seeking signs about whether he is the one. God does give us signs and confirmation, but we must be careful not to rely on signs alone. The Bible tells us that we are to walk by faith, not by sight 2 Corinthians 5:7 WEB. It is important to seek God's will in prayer and through His Word.
Lastly, you did not mention Jesus Christ in your request. It is only by the name of Jesus that we have access to God. The Bible tells us that there is no other name under heaven given among men by which we must be saved Acts 4:12 WEB. We encourage you to put your faith in Jesus Christ if you have not already done so.
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus, lifting up our sister who is in need of Your guidance, wisdom, and strength. Lord, we ask that You forgive her and the father of her child for any sexual immorality, and grant them a spirit of repentance. We pray for the father of her child, that You would deliver him from drugs and gambling, and grant him a heart of flesh that seeks after You. We ask that You would make it clear to our sister whether this man is Your will for her life, and if not, that You would bring a godly spouse into her life. We pray that You would heal their past hurts and give them divine intervention and hope for the future. We ask that You would be the center of their lives and that Your will be done in their situation.
In Jesus' name, we pray. Amen.
We encourage you to continue to pray and seek God's will for your life. Trust in Him, and He will direct your paths Proverbs 3:5-6 WEB. Stay strong in your faith and remember that God is faithful and He loves you and your child more than you can ever imagine.
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.
