Read: Exodus 23:27-33 NIV – “I will send my terror ahead of you – Bible Gateway
“Do not let them live in your land or they will cause you to sin against me.” Exodus 23:33 NIV

There is much in the news cycle around the world these days concerning countries with open borders even though they say their borders are secure. The main reason for closed and secure borders is for protection of their citizens. This is nothing new or distinct for the 21st century. We find an early prime example of a ‘no open borders’ policy from the pages of the Bible in the book of Exodus.
The Lord God established Israel’s border before they entered the Promised Land. “I will establish your borders from the Red Sea to the Mediterranean Sea, and from the desert to the Euphrates River.” (Ex.23:31 niv) Israel has well defined borders. They haven’t changed and a future day will come when Israel will possess all the land God has promised them.
What has caused a major delay in Israel not having all the land assigned to them was their unwillingness to finish the job of driving out the nations the Lord required them to do. They let them hang around within their borders. God specifically warned Israel if they did this their hearts would turn away from God. Israel would be influenced by those around them and would soon find themselves sinning against God. Israel didn’t secure their borders nor drive out all the heathen nations God required them to and we are still seeing the effects of that today.
Many Christians today are similar to ancient Israel in not having a ‘no open border policy.’ We let ourselves be influenced by things and even people God is instructing us to drive out of lives. The apostle Paul writes, “if anyone is in Christ, the new creation has come: The old has gone, the new is here!” (2Cor.5:17 niv) If we continue in our relationships as previously and do the things we did before as if nothing has changed, then nothing has changed! We have not closed our borders to the outside influences that can harm us. This will lead to damaging effects in our lives down the road. As a nation needs to secure its borders, Christians, especially new Christians need to seal off all negative influences that would lead them away from the Lord.
