The Lord Jesus: “Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. For if ye love them which love you, what reward have ye? do not even the publicans the same?” - - Matthew 5:43-46
Is not Jesus here warning against excluding the ones to whom we would in our fallen natures make exception? To love the unlovely, to carry the gospel to a people groups, to less those who curse us, this is the duty of His church, against which the very gates of Hell shall not prevail.
That is not the case here.
If there were equal outreach to Mahometans and Jews, I might think things were the case.
