“I say this because some ungodly people have wormed their way into your churches, saying that God’s marvelous grace allows us to live immoral lives. The condemnation of such people was recorded long ago, for they have denied our only Master and Lord, Jesus Christ.”
Jude 1:4 NLT
Just like John, Jude is stressing upon us to know what’s true about God and his word. This is the only way to recognize false teachings, people think theology is dry and they don’t study. Which makes them fall into false teachings. We must understand the fundamentals and just the basics of our doctrines of our faith so that we can recognize false doctrine and prevent those who want to follow or from just hurting themselves. So how do you know what’s true? We must meditate in God ‘s word and have it in our hearts and minds.
