God's vengeance is just because it is based on His holiness and the requirements of His law.
In the sermon, it is emphasized that God is a just God whose actions are rooted in righteousness. When Paul speaks of God's vengeance in 2 Thessalonians 1:8-10, he highlights that punishment fits the crime of rejecting God and disobeying His word. Since God's nature is perfectly holy, any disobedience towards Him incurs a just penalty. The notion of justice is not arbitrary; it flows from God’s character, meaning that His vengeance is the rightful response to mankind's rebellion and turning away from His commands. Therefore, the punishment mentioned is not disproportionate or excessive, but rather a fairest reflection of the gravity of sin against an infinitely holy God.
