Movies are influential in the mentality of people that are addicted to watching movies. There's danger in watching movies especially the ones that does not promote the teachings of Christ. As christians, it is not every movies that we are expected to watch. Movies can influence us negatively or positively depending on what it portrays.
As believers, there are movies which are not good for our spiritual life, they portrays lust of flesh, and other immorality of the world and watching them will lead us to sin because our thinking and action relates to what we see and hear.
Watching movies is not a sin, but as Christians we should watch movies that aligns with Godly values and does not negatively influence our spiritual, life instead it should be movies that talks about the teachings of Christ and also promote our spiritual life.
God bless you all 🙏.
