'Messenger' in the Bible

You yourselves are my witnesses that I stated, ‘I am not the Christ (the Messiah, the Anointed),’ but, ‘I have [only] been sent ahead of Him [as His appointed forerunner and messenger to announce and proclaim His coming].’

You do not have His word (Scripture) abiding in you [actually living in your hearts and minds], because you do not believe in Him whom He has sent.

Jesus answered, “This is the work of God: that you believe [adhere to, trust in, rely on, and have faith] in the One whom He has sent.”

I knew that You always hear Me and listen to Me; but I have said this because of the people standing around, so that they may believe that You have sent Me [and that You have made Me Your representative].”

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].”
