These are they which were not defiled with women; for they are virgins. These are they which follow the Lamb wherever he goes. These were redeemed from among men, being the first fruits to God and to the Lamb. - Revelation 14:4

“And whatever you do, do it heartily, as to the Lord, and not to men.” (Colossians 3:23)

God is a Spirit: and they that worship him must worship him in spirit and in truth. - John 4:24

The Lord Jesus says, “And why behold you the mote that is in your brother's eye, but consider not the beam that is in your own eye? Or how will you say to your brother, Let me pull out the mote out of your eye; and, behold, a beam is in your own eye? You hypocrite, first cast out the beam out of your own eye; and then shall you see clearly to cast out the mote out of your brother's eye.” (Matthew 7:3–5)
