Jesus Christ taught that morality and worship pleasing to God must come from the heart and that our greatest desire in life should be to seek not our own glory, but the glory of God. All this becomes clear from Jesus' disagreements with the religious leaders of his time. Jesus explained the errors of the Sadducees by the fact that they did not know the power of God, and, arguing with the Pharisees, He argued that the source of authority for us should be only God's Word without the addition of human traditions. It must be said that none of these disputes has yet ceased . And first of all, we should be interested in which side will we be on: the side of Christ or His opponents? Is our Christianity truly Christian or just a modern version of Pharisaism or Sadduceeism? John R. W. Stop is active as an evangelist and pastor, administrator and teacher.
