John 13:19-20

From now on I am telling you [what will happen] before it occurs, so that when it does take place you may believe that I am He [who I say I am—the Christ, the Anointed, the Messiah]. I assure you and most solemnly say to you, the one who receives and welcomes whomever I send receives Me; and the one who receives Me receives Him who sent Me [in that same way].”
