Nahum 1:7 - A God Of Refuge.

The LORD is good, a refuge in times of trouble. He cares for
those who trust in him,
Nahum 1:7 (NIV)

Nahum now emphasizes three comforting truths concerning God.
First, he is innately and inherently good. He can never be associated
with the opposite attribute. Second, he is the incomparable refuge
for his own in the time of their distress, "a bulwark never
failing," as Luther put it in his Reformation hymn. Third, he knows, in
the sense of loving, covenant care, all who have reposed faith in
him. [Wycliffe Bible Commentary]

The Lord is inherently good and a stronghold for the righteous
who seek refuge in his person. [New Bible Companion]

God assures us of His goodness and tells us we will be safe so
long as we trust in Him. [Wiersbe's Expository Outlines mod]

If people put their trust in God, they will experience Him as
good and as a defense against trouble. If they follow wickedness,
they will experience Him as destruction. [Passages Of Life SB]

When we think about the wrath of God, or divine vengeance, it's
helpful to remember that vengeance is directed against God's foes. Nahum
described God as "slow to anger," but reminds us that He will "not leave
the guilty unpunished."
God's wrath, or vengeance, is linked with a judicial act. It is
the right thing for God to punish the wicked. In fact, it is just as
right for Him to punish the wicked as it is for Him to care "for those
who trust in Him."
Let's not make the mistake of thinking that vengeance somehow
goes against God's character. As Nahum said, "The LORD is good" (v.
7). Yet "goodness" not only stands in contrast with evil, it stands
against evil! If God were not willing to take vengeance on the wicked,
and to treat them as objects of His wrath, God would not be good.
[The 365-Day Devotional Commentary]

To people who refuse to believe, God's punishment is like an
angry fire. To those who love him, his mercy is a refuge, supplying
all their needs without diminishing his supply. But to God's enemies
he is an overwhelming flood that will sweep them away. The
relationship we have with God is up to us. What kind of relationship will you
choose? [Life Application SB]
