They said to you, “In the last time there will be scoffers, following their own ungodly passions.” It is these who cause divisions, worldly people, devoid of the Spirit.
Do not let your adorning be external—the braiding of hair and the putting on of gold jewelry, or the clothing you wear— but let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God's sight is very precious.
By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already.
And I will give you a new heart, and a new spirit I will put within you. And I will remove the heart of stone from your flesh and give you a heart of flesh.
