Jude 1:3-4
Beloved, although I made every effort to write to you about the salvation we share, I felt it necessary to write and urge you to contend earnestly for the faith entrusted once for all to the saints. For certain men have crept in among you unnoticed — ungodly ones who were designated long ago for condemnation. They turn the grace of our God into a license for immorality, and they deny our only Master and Lord, Jesus Christ.

strains against Jude 1:3-4
The song opens by noting faith has faded in the world, then immediately replaces it with devotion to a lover rather than contending for the faith.
