John 3:11-12

And still you do not receive our testimony- you reject, refuse our evidence (that of myself and those who are born of the Spirit.) If I have told you of things that happen right here on earth, and yet none of you believes Me, how can you believe-trust Me, and adhere to Me, rely on Me-if I tell you heavenly things.  

The devil steals from the lost and leads them on a path of sin. A lie is believed until sin becomes second nature. Jesus and His word of salvation seem meaningless, and the lie becomes the truth. Plant the seed of Jesus and be an authentic believer. Someone else will water and another harvest but don’t give up on the lost.
