a verse for sinners

One of the best parts of Christianity is that is welcoming to sinners.  Romans 3:23 makes that clear along with Romans 6:23.  Often, we focus so much on the "sin" that we forget about the mercy!  Romans 3:24 (which follows right after Romans 3:23 is a good example of how crucial the grace message is).  I'm thinking today of a different verse, however.  It's found in 1 Timothy where Paul is instructing his disciple on practical ways the Gospel takes hold on a day to day basis.  I call this one "A verse for sinners" but it could be argued that all 31112 verses in the Bible are "a verse for sinners".  
1 Timothy 2:13   
if we are faithless, he remains faithful,
    for he cannot deny himself.
God's unchanging nature is a powerful comfort for us all!  Praise God!
