[13] Enter ye in at the narrow gate: for wide is the gate, and broad is the way that leadeth to destruction, and many there are who go in thereat. [14] How narrow is the gate, and strait is the way that leadeth to life: and few there are that find it! [15] Beware of false prophets, who come to you in the clothing of sheep, but inwardly they are ravening wolves. Matthew Chapter 7.
And that relates to your misinterpretation of God’s “vengance” how? You do realize God was not referring to His vengance but His people’s vengance which He did not want to consume them...leads to satan. God does not revenge...He Judges.
