Jesus warned His disciples that many would come in opposition to His message. As the church in Ephesus grew, some members of the church began to oppose the original message that Jesus Christ is the Son of God, sent to save those who will believe by grace through faith. These men and women who denied the Father and the Son worked to convince others of their errors. Pastor John emphatically writes that those who have left the flock of God are simply evidence of Jesus’ teaching. The opposition represents the reality of Satan and those who remain in Christ have confidence in the message of Jesus because they are the children of God.
