Beloved, while I was making every effort to write you about our common salvation, I felt the necessity to write to you appealing that you contend earnestly for the faith that was once for all time handed down to the saints. For certain people have crept in unnoticed, those who were long beforehand marked out for this condemnation, ungodly persons who turn the grace of our God into indecent behavior and deny our only Master and Lord, Jesus Christ.
Jude 1:3-4
