This is how is it originally played but I usually transpose it down 1 and 1/2 
steps and capo 3 to play it. It is easier to play. 

C5 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?C5 ? ? ? ? ?F5
There's a line that's been drawn through the Ages
? ? ? ? C5 ? ? ? ? ? ? C5 ? ? ? ? G5
On that line stood an old rugged cross
? ? ? ? C5 ? ? ? C5 ? ? ? ? F5 ? ? ? ? ? ? ? ?C5 ? ? ? ? ? ? G5 ? ? ? ? ? ?C5
On that cross a battle was raging, ?For the gain of man's soul or it's loss.
? ? ? ? ? ? ? ? ? ? ? ? ? C5 ? ? ? ? ? ? ?F5 ? ? ? ? ?C5 ? ? C5 ? ? ? G5
The Earth shakes with the force of the conflict, The Sun refuses to shine
? ? C5 ? ? ? ? ? ? ? ? C5 ? ? ? ? F5
For there hangs God's Son in the balance,
? ? ?C5 ? ? ? ? ? ? G5 ? ? ? ? ? C5
?And then thru the darkness He cries

(CHORUS:)
? ? ? ? ? ? ? ? C5 ? ? ? ? ? ?F5
It is Finished, the battle is over
? ? ? C5 ? ? ? ? ? ? ? ? ?C5 ? ? ? ? G5
It is Finished, there'll be no more war
? ? ? F5 ? ? ? ? ? ? ? ? ? ? ? ?C5
It is Finished, the end of the conflict
? ? ? ? ? ? ? ? ? ? G5 ? ? ? ?C5
It is Finished, and Jesus is Lord.

? ? ? ? ? ? ? ? C5 ? ? ? ? F5 ? ? ? ? ? ? ? C5 ? ? ? ? ? ?C5 ? ? ? ? ? G5
In my heart the battle was raging, Not all prisoners of war had come home.
? ? ? ? ? ? ? ? ? ? ? ? ?C5 ? ? ? ?F5
There were battle fields of my own making
? ? ? ? ? C5 ? ? ? ? ? ? G5 ? ? ? ? ? ?C5
I did not know that the war had been won.
? ? ? ? ? ? ? ? ? ? ? ? ? C5 ? ? ? ? ?F5
And then I heard that the King of all Ages,?
? ? C5 ? ? ? ? ? ? ?C5 ? ? ? ? ?G5
Had fought all the battles for me.
? ? C5 ? ? ? ? ? C5 ? ? ? ? ? F5
And victory was mine for the claiming,?
? ? C5 ? ? ? ? ? ? ?G5 ? ? ? ? C5
And now praise His Name I am free.
