Let's address the concerns you've raised and seek God's will together in prayer and through the Scriptures.
Firstly, it's important to understand what the Bible says about blood. Jehovah's Witnesses often refer to verses like Acts 15:20, "but that we write to them that they abstain from the pollution of idols, from sexual immorality, from what is strangled, and from blood," and Leviticus 17:10, "I will set my face against that soul who eats blood, and will cut him off from among his people."
However, these verses need to be understood in context. The early church addressed in Acts 15 was instructed to abstain from certain practices, including consuming blood, to maintain harmony with Jewish believers and to avoid offense. This did not imply that blood transfusions, which were not even a medical option then, were forbidden. In Leviticus, the context is about the Israelites' dietary laws and not about medical procedures.
Jesus Himself healed people, showing His care for physical well-being, including the woman with the issue of blood in Luke 8:43-48. Additionally, the apostle Paul discusses the freedom we have in Christ regarding various practices in 1 Corinthians 8 and 10, emphasizing that it is the intention of the heart and the conscience before God that matters.
Regarding the Jehovah's Witnesses' claim to be the only true church, we must remember what Jesus said in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" It is through faith in Jesus Christ that we are saved, not through affiliation with any particular denomination. As it is written in Romans 10:9-10, "that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes resulting in righteousness; and with the mouth confession is made resulting in salvation."
Let us pray for guidance and wisdom:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, seeking Your will and guidance. Lord, we pray for our friend who is dealing with the teachings of Jehovah's Witnesses and the misunderstandings surrounding blood donations and transfusions. Grant them wisdom and discernment to understand Your Word correctly.
Lord, we ask that You open the hearts and minds of the Jehovah's Witnesses family, especially the grandmother, to the truth of Your Word. May they come to know Jesus Christ as their Lord and Savior, and may they experience the freedom and joy that comes from a personal relationship with Him.
Father, we also pray for our friend's financial situation. We ask that You provide for their needs according to Your riches in glory. Guide them in their endeavors and help them make wise decisions that honor You.
In Jesus' name, we pray. Amen.
We encourage you to continue seeking God's will through prayer and the study of His Word.
