This song is in Eb key, that's what I got from hearing the music. Apologies if
there is any errors.

          Eb
In Christ alone will I glory
       Bb              Ab              Cm 
Though I could pride myself in battles won
	 Eb       
For I’ve been blessed beyond measure
    Bb                Ab           Bb    
And by His strength alone I’ll overcome
Ab                         Eb                         Ab  
Oh, I could stop and count successes like diamonds in my hands
          Fm                 Eb           Ab               Bb 
But those trophies could not equal to the grace by which I stand

[CHORUS]
          Ab   Bb         Eb
In Christ alone   I place my trust
   	     Fm           Bb      Eb 
And find my glory in the power of the cross
	 Ab    Bb             Gm     Cm 
In every victory   let it be said of me
   Ab                     Bb
My source of strength, My source of hope
	    Eb
Is Christ alone

In Christ alone do I glory
For only by His grace I am redeemed
For only His tender mercy
Could reach beyond my weakness to my need
And now I seek no greater honor in just to know Him more
And to count my gains but losses to the glory of my Lord

[CHORUS]

[CHORUS] (final part) – up to F key

	   Bb C          F
In Christ alone I place my trust
   	     Gm          C         F
And find my glory in the power of the cross
	 Bb     C           Am     Dm
In every victory let it be said of me
   Bb                     C  
My source of strength, My source of hope
	    F
Is Christ alone
