The onus is on God's children to embrace truth and the ministry He has called to preach the gospel.  To reject a man called by God is to reject both Christ and the Father! When commissioning the disciples, Jesus said, "He that receiveth whomsoever I send receiveth me; and he that receiveth me receiveth him that sent me  (Matthew 10:40). But there is a caveat, for the reverse is also true. Anyone who rejects Christ's ministry, Jesus warned  "it will be more tolerable for the land of Sodom and Gomorrah on the day of judgment." (Matthew 10: 14-15)
