We have been practicing a song...

I'm having trouble getting the notes, but I realized that I am having even more trouble with the words!  I think we often sing a song because "we like it", which to me is very shallow.  I believe music conveys more than just fuzzy, warm feelings!  The music we fill our minds and hearts with, the music we desire to listen to, the music we sing...flows from the abundance of our heart. I was reading in Luke 6...and came upon verse 39-46..."...for of the abundance of the heart his mouth speaketh."  The book of Proverbs and James are filled with verses on this truth.  You cannot sing the world's music all week long and then try to sing Godly music on Sunday and expect God to bless it!  And so I sit here...wondering...if my heart is right, my motives are pure, and my words truthful...as I prepare to stand and sing with other ladies...before our church congregation...but more importantly...before my Lord and Savior.  This song is making a statement...that I really don't think we take seriously!  "It's a nice song for Easter." And my heart sank.
Galatians 2:20
"I am crucified with Christ;  therefore, I no longer live.  Jesus Christ now lives in me... 
Embrace the cross where Jesus suffered, Tho' it will cost all you claim as yours.  Your sacrifice will seem small beside the treasure:  Eternity can't measure what Jesus holds in store. 
Embrace the love the cross requires:  Cling to the One whose heart knew every pain.  Receive from Jesus fountains of compassion:  Only He can fashion your heart to move as His.  O wondrous cross, our desires rest in you.  O Lord Jesus, make us bolder to face with courage the shame and disgrace You bore upon Your shoulder. 
Embrace the life that comes from dying:  Come trace the steps the Savior walked for you.  An empty tomb concludes Golgothat's sorrow.  Endure, then, till tomorrow your cross of suffering.  Embrace the cross."
But what about Galatians 2:21?
I guess, I find myself struggling with what I know to be truth...
I find myself struggling with what I see and hear...
I don't want to frustrate the grace of God.  I don't want to add to salvation.  I don't want to trample on the evidence of what God has done and is doing in my life.  I have been redeemed by the blood that Jesus Christ shed on the cross!  Romans 3:24  Because I have been bought, I am not my own!  Romans 6:14-23
My testimony is important!  Maybe that is why my heart sank...and why I continue to struggle with this song.
