If a man is a believer in Christ, but his wife is not, can she receive salvation from God based on her husband’s commitment to our Lord and Saviour?
Sorry, there’s no scripture to support that view. In fact Christians are admonished not to marry unbelievers because as Paul wrote, “How do you know, husband, whether you will save your wife?” (1 Cor. 7:16) Each one of us is responsible for our own salvation. No one can get it for us.
