How do we know false teachers are ordained to condemnation?

In Jude 1:4, we read that certain ungodly men have been 'before of old ordained to this condemnation.' This speaks to the sovereignty of God in all matters, including the existence of false teachers within the church. Such individuals are not merely random threats; their presence serves God's ultimate purpose in allowing trials for His people. Their fate is predetermined by God's decree, reinforcing that God works all things, including the actions of these men, according to His divine counsel. This assertion underlines the seriousness of their influence on the faith and serves as a warning to believers to remain vigilant.
