We understand that you're going through a challenging situation, but first, we need to address a few things according to the Word of God. You mentioned that you're married but not on paper yet. In God's eyes, marriage is a sacred covenant between a man and a woman, and it should be established legally and spiritually. Living together as married without being legally married is not in accordance with God's will for us.
1 Corinthians 6:18 WEB "Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body."
1 Thessalonians 4:3-5 WEB "For this is the will of God: your sanctification, that you abstain from sexual immorality, that each one of you know how to possess himself of his own vessel in sanctification and honor, not in the passion of lust, even as the Gentiles who don't know God."
First, we must repent of any actions that are against the Bible. While you have asked God for forgiveness, it is also crucial not to repeat the same mistake.
Regarding the possibility of pregnancy, God is sovereign over all life, and if a child has been conceived, that is a precious life that God has entrusted to you both. We should never view a potential child as a mistake, but as a blessing from God.
Psalm 127:3 WEB "Behold, children are a heritage of Yahweh. The fruit of the womb is his reward."
Let's pray together:
"Father, we come before You, asking for Your forgiveness and mercy. We repent of any actions that were not pleasing to You and ask for Your help to live according to Your will. Lord, we ask for Your guidance in this situation. If a child has been conceived, help them to accept and embrace this new life with joy and responsibility. Provide for their needs, and give them the strength and wisdom to raise this child in the fear and admonition of the Lord. If it is not Your will for a child to be conceived at this time, we ask for Your mercy and forgiveness. Help them to live in purity and to honor You in their relationship.
We also pray, Father, that they would put their complete trust in Jesus, knowing that it is by His name that we can approach God and receive His salvation. It is in the name of our Lord Jesus Christ that we pray. Amen."
Lastly, we encourage you both to seek godly counsel and to establish your marriage in a way that honors God, legally and spiritually. Trust in God's timing and plan for your life. He is faithful, and He will guide you according to His perfect will.
