Would Lamb of God also be a title, seeing He is not a literal Lamb, but God the Son?
To me it's His title...the Lamb
of God.
The sacrificial "lamb" for His people ( Isaiah 53 ).
Did Jesus choose to be the Lamb of God or has He always been the Lamb of God?
It says that He is the Lamb, and so He is ( John 1:36 ).
It says that He is the Lamb slain ...when was He foretold to have been slain? From the foundation of the world ( 1 Peter 1:20, Revelation 13:8 ), my friend.
Some theologians have gone so far as to envision an agreement made, before the world began, between the Father and the Son...
in which the Father gave a people to His Son, and the Son became surety for them and them alone.
This was all planned from the start, and I happen to agree with them, for the most part;
However, I find it wise not to go beyond what the Scriptures say and to teach theories ( or even "almost-facts )
as fact,
as even careful ( and what seems to us as "sensible" ) conjecture can often go beyond the confines of what the Lord has given to us in His word.
That said, we
can know that Jesus, who is Emmanuel ( "God with us", Matthew 1:23 ),
is the Son of the living God ( Matthew 16:20 ).
The Father sent Him ( 1 John 4:14 ) to be the Saviour of the world.
That He is and was the Son of God from the beginning ( 1 John 1:1 ) appears to be in dispute among some people on this board, but to me it is not:
" In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made. " ( John 1:1-3 ).
In the above,
I see that all things were made by the Son, and outside of the Son was not made anything that was made...
So, this should settle the fact of whether or not He was the Son from creation ( and not "the first created being", for example, as some have taught ), or was part of the Godhead and
then "became the Son" when He departed Heaven and was born of a woman.
That the Godhead
is the Father, Son and Holy Spirit, seems to be in dispute among some here.
