2 Nephi 31:14

But behold, my beloved brethren, thus came the voice of the Son unto me, saying, After that ye have repented of your sins, and witnessed unto the Father that ye are willing to keep my commandments, by the baptism of water, and have received the baptism of fire and of the Holy Ghost, and can speak with a new tongue, yea, even with the tongue of Angels, and after this, should deny me, it would have been better for you, that ye had not known me.

But the Son’s voice came to me and said: “After you have turned back from your sins and shown the Father you are willing to keep my commandments by being baptized in water, and after you have gotten baptism of fire and of the Holy Spirit, and can speak with a new voice like the angels do, if after this you say you don’t know me anymore, it would have been better if you had never known me at all.”

But the Son’s voice also came to me with this warning: “After you’ve repented, after you’ve shown the Father through baptism that you’ll keep my commandments, after you’ve received the baptism of fire and the Holy Spirit and can speak this new language—the language of angels—if after all that you turn your back on me, it would have been better if you’d never known me at all.”
