Observation: As the Lord meets Moses face to face and gives him the commands again, he tells him that he will drive out the foreign nations from Canaan. With this, they are warned not to make align in any way with those nations, or else they will be tempted to follow the ways of those nations. For example, if you make a treaty with them, they will celebrate the treaty with a feast to their gods, and Israel would join in that feast. Likewise, if they intermarry, the foreign spouse will bring their ways into the home.
In this way, the Lord describes these foreign influences as a "snare". They don't themselves kill you, but instead they trap you - perhaps even as a trap or as a hidden and deceptive method of capture - to then take you to a place and outcome of death.
Application: I live in a place and time where everything is seemingly a snare. We cannot watch television, or walk down the street, or do a Google search, without something potentially sinful - or at least outside of the Lord's will and law - popping up. So I must ask myself ... have I made a treaty with the world?
While I can say that 'no' I have not signed some agreement between myself and some people-group, I have made certain mental agreements about coexisting in society, under certain norms. These include things like subscribing to streaming services, using the internet, and having social media accounts. These expose me to opportunities to sin, letting those influences into my home. And in many ways, I then normalize and allow problematic information and content into my life.
These are the modern-day snares. We are only just beginning to really understand this, I feel, as we now see the impact on not just individuals but upon entire generations. Even entities with no faith now see the harm of some of these systems of influence.
As a Christian, I should be removing myself more and more from them. It may not be possible (for example) to not use the internet in today's world, just like it wasn't possible for Israel to enter Canaan without seeing the behaviors of Ammonites and Hittites and Jebusites. However, there is a difference between seen such things, and engaging in the same activities. As one moves toward such things ... the snares arise.
Prayer: Lord, I know I fall into the traps of this world, and it is true that those traps existing on screens now days. During this season, may I fast from these elements of the world, and disassociate my mind from them. Amen.
