The Bible says "Before I formed you in the womb I knew you." God has known us even before the creation of time. And despite our sin and knowing all the things we were (and still are) going to do against Him, he still loved us enough to give His life away for us. He has always known and loved us.

I don't know how to explain it
But I know that words will hardly do
Miracles with signs and wonders
Aren't enough for me to prove to you

Chorus:
Don't you know that I've always loved you
Even before there was time
Though you turn from me
I'll tell you still
Don't you know that I've always loved you
And I always will

Greater love has not a man
Than the one who gives his life to prove
That he would do anything
And that's what I'm going to do for you

Chorus
