Many Christians are idiots. The anti-Christ is anything we (all of us) each express in outward visible fashion which isn’t Christ.
For example, God is kindness. Kindness is invisible, we can’t see kindness. But we can see the outward visible expression of kindness through you and the outward visible expression of kindness towards others is Christ the Son of God. When we are physically born we already know how to be unkind. Over time, as we grow up, we learn how to be kind. HEARing how to be kind…and expressing kindness for others to SEE is the resurrection and coming of Christ in each of us. Whereas, expressing unkindness is the crucifying of Christ by expressing the antichrist.
So if Christians fall for a fake coming of Christ, which many will, they should have not listened to their religion and studied scripture themselves. A few know the Truth.
