Rock of Ages

What an amazing hymn.  If you're not sure what exactly Christ did for you with His death, take a look at this hymn.  If you still think that something other than Christ can save you, take a look at this hymn.  It gives good insight on how broken we are, and how it is only through Christ's blood that we can gain sanctification.  Christ's blood is the double cure--from sin's guilt and power.  Let Christ be glorified for His great work, and I hope this can make you ever thankful for His saving work. 

Rock of Ages, cleft for me, let me hide myself in thee; let the water and the blood, from thy wounded side which flowed, be of sin the double cure; save from it's guilt and power. Not the labors of my hands can fulfill thy law's commands; could my zeal no respite know, could my tears forever flow, all for sin could not atone; thou must save, and thou alone. Nothing in my hand I bring, simply to the cross I cling; naked, come to thee for dress; helpless, look to thee for grace; foul, I to the fountain fly; wash me, Savior, or I die. While I draw this fleeting breath, when mine eyes shall close in death, when I soar to worlds unknown, see thee on thy judgment throne, Rock of Ages, cleft for me, let me hide myself in thee.
