Suffer Me Not to be Separated From Thee

I'm continuing with looking at the Anima Christi prayer. If you want a more in-depth theological look at it, I highly recommend Micah's posts over at The Ranter's blog. Here's the full text of the prayer:

Soul of Christ, sanctify me
Body of Christ, save me
Blood of Christ, inebriate me
Water from the side of Christ, wash me
Passion of Christ, strengthen me
O good Jesus, hear me
Within Thy wounds hide me
Suffer me not to be separated from Thee
From the malicious enemy defend me
In the hour of my death call me
And bid me come unto Thee
That with thy Saints I may praise Thee
For all eternity
Amen

Suffer me not to be separated from Thee

 I see this as a supplication that we will not walk away from God, for nothing can separate us God unless we choose to walk away (Romans 8:38-9).  Since we don't lose our free will when we become Christians, we can choose to walk away from God at any time, thereby separating ourselves from Him.  This part of the prayer reminds me of the injunctions to persevere to the end so that we may be saved (Matthew 24:13).  I pray that I will persevere, by the grace of God.  Suffer me not to be separated from Thee, O Lord!
