Whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into Hell.
–Matthew 5:28-29 (KJV)–

Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
–Matthew 7:21 (KJV)–

They were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
–Acts 2:4 (KJV)–
