We can be certain of the Second Coming in spite of scoffers, knowing God has fulfilled His Word in the past and He is patient, giving people plenty of time to repent.
False teachers and those who follow them face judgement and would have been better off not to have known the Gospel and turn their backs on it.
The Lord knows how to rescue the godly from trials and to hold the unrighteous for punishment on the day of judgment.
False teachers deceive people for personal profit, deny the Lord Jesus Christ, but will certainly be destroyed.
Trusting in yourself will lead to eternal disappointment but fully trusting in God will lead to eternal joy.
