1) Check out the wikipedia article on the "Antichrist".
Christians throughout history have spent much of their effort on trying to identify the Antichrist. How would the church benefit if we knew the identity of the Antichrist?
Is it crucial for Christians to know who the identity of theAntichrist? Even if we never figure out for sure who the Antichirst is, we can still follow the one TRUE Christ.
2) Read 2 Thessalonians 2:8-10.
Satan will use his power to support the Antichrist. There will be miracles, and false teachers that will decieve many. What can we use to test the miracles and teachings of the Antichrist? Maybe another way to ask this question is: what do we trust in above miraculous signs, and human teachings?
It is the Word of God, living and active and sharper than any double edged sword. The Word of God will cut through the lies of Satan.
3) Read 2 Thessalonians 2:11-12
Jesus will come in glory and overthrow this villian with the breath of his mouth. In other words, the glory of God will outshine the best attempts of Satan.
Consider this: When Jesus was born in the flesh it was part of the most humble expression God could make to man. Satan, on the other hand, will raise a glorious Antichrist. Isn't it interesting that God can use his most humble effort to overthrow Satan's best?
