If God selected those who would saved, how is this loving and just?

God does not actively suppress faith in non-believers. He simply passes over them. It is important to point out that the Bible speaks in terms of "justice." Everyone who hears the salvation message makes his or her own choice to believe or not believe the gospel.

"All have sinned and fall short of the glory of God" (Romans 3:23)

"For the wages of sin is death, but the gift of God is eternal life through our Jesus Christ our Lord" (Romans 6:23).
