And if they don't, we assume that they are against us and, consciously or unconsciously, take steps to hinder them. But Jesus said that we are not to hinder them. It is important to recognize that Jesus did not say that we had to join the church or ministry of everyone who is not against us. There may be some very good doctrinal reasons why we could never completely enjoy happy fellowship in such a group. And the Lord did not say that we had to change our convictions about how the Lord's work should be carried out.
Christians have strong convictions, for example, as to financial and administrative procedures.
Forms of church government and modes of baptism are other areas where there is considerable conviction. Finally, the Lord Jesus did not say that we had to sponsor the ministries of Christians who don't do it or see it our way. Some Christians disagree as to how best to carry out the great commission on the foreign mission field or the inner city, for example. Furthermore, Christians have varying concerns for the work of the Lord. Some are more concerned about literature distribution than about TV and radio evangelism.
