Borders Why do Christians need them?

Nations have borders because man has fear of other men. God created mankind out of love. So if we are a Christian nation why do we have borders and fear of other men.  1 John 4.16 "And we have known and believed the love that God hath to us. God is love and he that dwelleth in love dwelleth in God and God in him."  Ellert Clemenson 2388 HWY 135 #8 Gunnsion Colorado 81230 send cash need help going back to school. Where is the love?
