We are truly sorry to hear about the pain and distress your family caused on what should have been a joyous day of baptism. We will pray for you and your family, and we appreciate your desire to seek godly counsel on this matter.
Firstly, we commend you for forgiving your family, as Ephesians 4:32 tells us, Be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you. However, forgiveness does not mean that we ignore or overlook the sin that has been committed. It is right to desire that your family be convicted of their sin and repent. As the word of God says If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness. 1 John 1:9 (WEB).
It is clear from your message that your family has sinned against you and ultimately against God. Their actions were not according to God's will but driven by their own desires and the influences of darkness. As it is written, in For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Ephesians 6:12 (WEB).
Now, regarding what you should do moving forward, we advise the following:
1. **Pray**: Continue to pray for your family's conviction and repentance. Pray that God softens their hearts and opens their eyes to the truth. As the word of God says in And the lord's servant must not be quarrelsome but kind to everyone, able to teach, patiently enduring evil, correcting his opponents with gentleness. God may perhaps grant them repentance leading to a knowledge of the truth, and they may come to their senses and escape from the snare of the devil, after being captured by him to do his will. 2 Timothy 2:24-26 (WEB).
2. **Set boundaries**: Even though you have forgiven them, it is wise to set boundaries to protect yourself from further harm. You do not have to tolerate their abusive behavior. As it is written, If it is possible, as much as depends on you, live peaceably with all men. Romans 12:18 (WEB).
3. **Trust God**: Trust that God is working in this situation, even if you cannot see it. He can turn even the most difficult circumstances into good as written in And we know that all things work together for good to them that love God, to them who are the called according to his purpose. Romans 8:28 (WEB).
4. **Seek support**: Reach out to your church community for support and guidance. They can provide you with practical help and pray with you.
5. **Share the gospel**: Continue to share the truth of God's word with your family. Be patient, gentle, and loving in your approach.
Let's pray:
Heavenly Father, we come before You today to lift up our sister in Christ who has been deeply hurt by her family. Lord, we ask that You convict her family of their sin and bring them to repentance. Open their eyes to see the truth of Your word and the love of Your daughter for them. Help her to continue to forgive, to set healthy boundaries, and to trust in You. Surround her with Your love and protection, and give her the support she needs from Your body of believers. Lord we also pray for their salvation if they do not yet know Jesus. In Jesus' name, we pray. Amen.
Lastly, we want to remind you that it is only in the name of Jesus that we have access to God the Father. It is only through the name Jesus that we can be saved. As it is written for there is no other name under heaven given among men by which we must be saved. Acts 4:12 (WEB). Continue to stand firm in your faith and proclaim Jesus Christ as continued baptism. We are here to support you.
