Galatians 6:17

always carrying about in the body the dying of Jesus, so that the life of Jesus also may be manifested in our body.

that I may know Him and the power of His resurrection and the fellowship of His sufferings, being conformed to His death,

The one who believes in the Son of God has this witness in himself. The one who does not believe God has made Him a liar, because he has not believed in the witness which God has borne witness about His Son.

And he causes all, the small and the great, and the rich and the poor, and the free men and the slaves, that they be given a mark on their right hand or on their forehead,

and that no one will be able to buy or to sell, except the one who has the mark, either the name of the beast or the number of his name.
