What does the Bible say about praying for others?

In 1 John 5, the apostle John instructs believers about the importance of prayer, particularly when it comes to seeking life for those who have sinned. He highlights that if anyone sees a brother sinning a sin that is not unto death, he should ask, and God will give him life. This emphasizes the role of intercessory prayer in the Christian community. However, it also warns against praying for those who reject Christ and are in a state of unbelief, as their sin unto death cannot be remedied apart from faith in Jesus. When praying for others, it is vital to seek their spiritual well-being and growth in faith, asking God to open their eyes to the truth of the gospel.
