1 John 5:19 We know that we are from God, and the whole world lies in the power of the evil one.
Joh 17:15 I do not pray that you take them out of the world, but that you keep them from the evil.
Joh 17:16 They are not of the world, even as I am not of the world.
For first-century Christians, the world was a dangerous place. Only by seeking first God’s righteousness could they endure with their integrity intact. Most did endure, but a few were diverted from “the path of righteousness.” (Prov. 12:28; 2 Tim. 4:10) Is the world safer for Christians today? By no means! It is even more corrupt than it was in the first century. In addition, Satan wages vicious warfare against Christians and those who support them. (Rev. 12:12, 17) While no part of the world, Christians have to live in it. (John 17:15, 16) And they have to preach in it to seek out rightly disposed people and teach them to be disciples of Christ. (Matt. 24:14; 28:19, 20) Therefore, since Christians cannot entirely avoid the corrupting influences in this world, they have to resist them.
