It is because they are like-minded with him! John writes:

"Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.... "Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time" (1 John 2:15-18).

John is warning us that those who still love the things of this world have opened themselves to the spirit of antichrist. He's saying, "You know these are the last days because so many are full of the covetous antichrist spirit!"

"Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son"

(1 John 2:22). The apostle adds, "If you have not come under the total Lordship of Jesus if YOU do not acknowledge Him in all your ways then you have opened yourself up to this spirit of evil!"

Beloved, if you are serving Jesus only 50 percent or even 90 percent then you are denying His full salvation. You aren't serving Him with all your heart, mind, soul and body. And you have opened up an inroad for the antichrist spirit to come in!

It's not enough to say, "I believe Jesus was God in flesh." Rather, we must say, "Jesus, You are God in flesh in me. You have all power and authority over lust and sin. And I yield to You completely!"
