We understand your concern and the deep bond you shared with your sister. It's important to remember that God's mercy and grace are boundless, and He desires for all to come to the knowledge of His truth.
Firstly, let's address the most important aspect of your request. You mentioned that neither of you talked about God or Jesus Christ. It's crucial to understand that it is only through Jesus Christ 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.
And in Acts 4:12 WEB:
There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved.
Since you mentioned that you both believed yourselves to be witches, we must address this as well. This is a grave error and a sin against God. Repentance and turning away from such beliefs and practices is essential. As it is written in Deuteronomy 18:10-12 WEB:
There shall not be found with you anyone who makes his son or his daughter to pass through the fire, one who uses divination, one who practices sorcery, or an enchanter, or a sorcerer, or a charmer, or a consulter with a familiar spirit, or a wizard, or a necromancer. For whoever does these things is an abomination to Yahweh
You have taken the right step by returning to your faith and seeking God's forgiveness. Remember, in 1 John 1:9 WEB:
If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness.
Regarding your sister, we cannot know for certain what was in her heart at the moment of her passing. However, we can take comfort in the knowledge that God is merciful and just. We can pray that she found peace with God before her death.
Let us pray together:
Heavenly Father, we come before You in the name of Jesus Christ, asking for Your mercy and grace. We pray for Thruilarian's sister, that if she did not know You in life, You would have mercy on her soul. We thank You for the forgiveness and restoration that Thruilarian has experienced, and we ask that You continue to guide and strengthen them in their walk with You. Help them to trust in Your goodness and Your plan, even in the face of uncertainty. Give them peace and comfort in their memories of their sister, and help them to rest in the knowledge that You are a just and loving God. In Jesus' name, we pray. Amen.
Moving forward, focus on your own walk with Christ and share the good news of the gospel with others. Trust in God's plan and remember that His love and mercy are boundless. It is never too late to turn to Him and seek His forgiveness.
