As a Christian, I think building the wall on our southern border is a good idea. Why? You ask. Is it biblical? Yes, it actually is. I will share a few Bible verses on building walls though there are many and share my thoughts on why I think God would support it, but first, I want to share my thoughts.
Do you live in an apartment complex with walls surrounding it? Do you have bars on your windows or lock your doors? Why? It’s most likely to protect the loved ones and valuable property within, am I correct? It’s not about keeping people out who wouldn’t do damage. They would knock on the door to gain entrance. It’s about keeping those out who intend harm. Correct?
It’s the same with the southern border wall. If people want to “knock” and come in legally, we are all for it. It’s not racist, bigoted or anything else to want that. We want people to come, only we want to them to do it legally. If you will break a law to come in, who is to say you won’t break more laws. Legal immigrants go through a process of teaching them our laws. Illegals only know former laws. Many laws in foreign countries can be broken if the police are bribed.
Every city in Biblical times was surrounded by a wall. They wanted to protect the people that lived within from attacks because they valued them. Here are some verses on building the wall in Jerusalem:
2 Chronicles 32:5 And he took courage and rebuilt all the wall that had been broken down and erected towers on it, and built another outside wall and strengthened the Millo in the city of David, and made weapons and shields in great number.
Nehemiah 2:17 Then I said to them, “You see the trouble we are in: Jerusalem lies in ruins, and its gates have been burned with fire.Come, let us rebuild the wall of Jerusalem, and we will no longer be in disgrace.”
Ezekiel 42:20 He measured it on the four sides; it had a wall all around, the length five hundred and the width five hundred, to divide between the holy and the profane.
Revelation 21:12-19 It had a great and high wall, with twelve gates, and at the gates twelve angels; and names were written on them, which are the names of the twelve tribes of the sons of Israel. There were three gates on the east and three gates on the north and three gates on the south and three gates on the west. And the wall of the city had twelve foundation stones, and on them were the twelve names of the twelve apostles of the Lamb. The one who spoke with me had a gold measuring rod to measure the city, and its gates and its wall. The city is laid out as a square, and its length is as great as the width; and he measured the city with the rod, fifteen hundred miles; its length and width and height are equal. And he measured its wall, seventy-two yards, according to human measurements, which are also angelic measurements. The material of the wall was jasper; and the city was pure gold, like clear glass. The foundation stones of the city wall were adorned with every kind of precious stone The first foundation stone was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;
The final verse, I believe speaks of the New Jerusalem prophesied by John the Disciple. If our future as Christians is the New Jerusalem and a New Earth and it has a wall, why shouldn’t we build a wall to protect Americans from those who intend to hurt it? Why shouldn’t we protect those within?
