For even His brothers did not believe in Him.
John 7:5
My guess is that if you are saved, and understand salvation and what awaits those who are not saved, you are concerned for family and friends who are not trusting in and following Jesus. You may even feel desperate. Let me give you three reasons to take heart.
First, you are not the only one who has unbelieving loved ones. So did Jesus. And He was the perfect witness for the gospel. Thankfully, at least two of Jesus’ unbelieving brothers ended up believing. James and Jude became leaders in the early Church and wrote the New Testament books that bear their names.
Second, Jesus will save His people. Unlike Jesus, we are often not the best witnesses. We fail. Sometimes often. Sometimes in big ways. The good news is that while our words and lives do matter, ultimately no one is lost because of our failures. God is faithful to save His people, using folks like us—warts and all!
Third, God hears our prayers and loves our loved ones more than we do. Be concerned about your testimony, because it does matter. But most of all, pray. Only God can change a person’s heart. Pray that He will do just that. And trust that according to His good pleasure, as He has been gracious to you, He may be gracious to those you love and care about.
