Paul feels called of God to head to Jerusalem despite what he has been told by the Spirit will be trouble. His friends, his brothers and sisters in Christ, try to dissuade him, even by claiming that their opposition is compelled by the Spirit. Both can’t be the voice of God. Speaking into each others lives is “part and parcel” of being the Body of Christ however we need to guard against allowing our biases to influence our advice.
