I guess part of the problem we have is becoming negative, looking at problems and giving up.
I recall the story of a farmer who became a Christian. He worried about his family so he spent
hours walking his back 40 acres praying this following prayer until his whole family was saved.
No arguing necessary.
 
Acts 16:29
 
The jailer called for lights, rushed in and fell trembling before Paul and Silas.
30 He then brought them out and asked, "Sirs, what must I do to be saved?"
31 They replied, "Believe in the Lord Jesus, and you will be saved—you and your household." 
32 Then they spoke the word of the Lord to him and to all the others in his house.
33 At that hour of the night the jailer took them and washed their wounds; then immediately he and all his family were baptized.
34 The jailer brought them into his house and set a meal before them; he was filled with joy because he had come to believe in God—he and his whole family.
