I love to sing about Jesus's sacrificial love for us as demonstrated and fulfilled by his substitutionary death on the cross. I particularly love this hymn and so I pray it ministers to you. In brackets you'll find references to relevant Scripture that informs and inspires this song. I've also added below a passage from Isaiah 53. I pray this blesses you as it does me, as both a song of worship and a prayer.
How deep the Father's love for us,
How vast beyond all measure,
That He should give His only Son
To make a wretch His treasure. [John 3:16]
How great the pain of searing loss –
The Father turns His face away,
As wounds which mar the Chosen One
Bring many sons to glory. [Col. 3:1-4; Rev. 5:6-10]
Behold the man upon a cross,
My sin upon His shoulders;
Ashamed, I hear my mocking voice
Call out among the scoffers. [Isa. 53:3-4; I Timothy 1:12-17]
It was my sin that held Him there
Until it was accomplished;
His dying breath has brought me life –
I know that it is finished. [John 19:30]
I will not boast in anything,
No gifts, no power, no wisdom;
But I will boast in Jesus Christ,
His death and resurrection. [I Cor. 1:31; 2 Cor. 11:30; Gal. 6:14; Eph. 2:1-9]
Why should I gain from His reward?
I cannot give an answer;
But this I know with all my heart –
His wounds have paid my ransom. [Isa. 53:4-5,12; Col. 2:11-14]
3 He was despised and rejected  by men;
a man of sorrows,  and acquainted with  grief; 
and as one from whom men hide their faces 
he was despised, and we esteemed him not.
4 Surely he has borne our griefs
and carried our sorrows;
yet we esteemed him stricken,
smitten by God, and afflicted.
5 But he was wounded for our transgressions;
he was crushed for our iniquities;
upon him was the chastisement that brought us peace,
and with his stripes we are healed.
6 All we like sheep have gone astray;
we have turned—every one—to his own way;
and the Lord has laid on him
the iniquity of us all.
7 He was oppressed, and he was afflicted,
yet he opened not his mouth;
like a lamb that is led to the slaughter,
and like a sheep that before its shearers is silent,
so he opened not his mouth.
8 By oppression and judgment he was taken away;
and as for his generation, who considered
that he was cut off out of the land of the living,
stricken for the transgression of my people?
9 And they made his grave with the wicked
and with a rich man in his death,
although he had done no violence,
and there was no deceit in his mouth.
10 Yet it was the will of the Lord to crush him;
he has put him to grief; 
when his soul makes  an offering for guilt,
he shall see his offspring; he shall prolong his days;
the will of the Lord shall prosper in his hand.
11 Out of the anguish of his soul he shall see  and be satisfied;
by his knowledge shall the righteous one, my servant,
make many to be accounted righteous,
and he shall bear their iniquities.
12 Therefore I will divide him a portion with the many, 
and he shall divide the spoil with the strong, 
because he poured out his soul to death
and was numbered with the transgressors;
yet he bore the sin of many,
and makes intercession for the transgressors.
