The enemy uses the world to invade and attack the church, duh! We surely know that. But it is more dangerous to know this and not deal with it. Jesus say, "Repent therefore; but if not, I am coming to you quickly, and I will make war with them with the sword of My mouth." (Revelation 2:16) "Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a prostitute? Absolutely not! Or do you not know that he who is joined to a prostitute is one body? For He says, “The two shall be one flesh.” But he who is joined to the Lord is one spirit." (1 Corinthians 6:15-17) In these Last days let us not join ourselves to anything but the Lord. This is the church of His choosing.
