“When God is asked: “Remember your great mercy and love,” he is being asked to act according to his character. When someone asks God to “remember not [my] sins,” he or she is asking that God would not act on what he knows. Therefore, to say that the Israelites “forgot” God is to say that they no longer were controlled by what they knew. We could put it another way. Though they knew who God was and what he wanted, those things were not real to them.” ― (Timothy J. Keller, Judges For You)
“Therefore the LORD was very angry with Israel and said, “Because this nation has violated the covenant I ordained for their ancestors and has not listened to me, I will no longer drive out before them any of the nations that Joshua left when he died. I will use them to test Israel and see if they will keep the way of the LORD and walk in it as their ancestors did. – (Judges Chapter Two)
“But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.” – (Revelation 21:8)
” If you ever forget the Lord your God and follow other gods and worship and bow down to them, I testify against you today that you will surely be destroyed. Like the nations the Lord destroyed before you, so you will be destroyed for not obeying the Lord your God.” (Deuteronomy 8: 19-20)
There is a way which seems right unto a man, But the end thereof are the ways of death. Even in laughter the heart is sorrowful; And the end of that mirth is heaviness. The backslider in heart shall be filled with his own ways: And a good man shall be satisfied from himself. The simple believeth every word: But the prudent man looks well to his going. A wise man fears, and departs from evil: But the fool rages, and is confident. – (Proverbs 14:12-16)
