John saw Jesus coming toward him and said,
"Look, the Lamb of God, who takes away the sin of the world!" John 1:29
(Words/Music by Michael Smith)

"On His robe and on His thigh He has this name written:
  KING OF KINGS AND LORD OF LORDS" Revelation 19:16
(Ingrid DuMosch & the London Fox Singers)

The Golden City (Mal Pope & Julie Costello)

Soon your trials will be over
Offered up by mercy's hand
A better view from where you stand
Going to another land
The sweetest welcome from the Father
Gathered up and carried home
We are past this time of waiting
Come let us bow before Your throne
CHORUS:
We will meet in the Golden City in the New Jerusalem
All our pain and all our tears will be no more
We will stand with the hosts of heaven
And cry holy is the Lamb
We will worship and adore You evermore
Never can the powers of darkness
Neither death nor even life
Let nothing ever separate us
From the holy love of God
Holy, holy, holy is the Lamb
Holy, holy, holy is the Lamb

A worship song originally written as a traditional hymn by John M. Harris, made into a contemporary tune by Andy Bromley. The lyrics speak about the wonders of finding our salvation in Christ and what that means in relation to our sin, our relationship with God, and our eternity spent with Him.
Romans 3:21-24  tells us that there is a righteousness from God that comes through faith in Jesus Christ. All of us have sinned, but have been justified freely by God's grace through Christ's sacrifice for us. What this means is that our sins have been atoned for, that we are now God's children because of Christ's righteousness, and that we shall reign with Him in eternity because of the salvation Christ has brought us. Indeed this is something that we should be praising God for, declaring that He is our wonderful Saviour.
