The fact that God does and will judge us is one of the Bible’s key teachings, without which the significance of other key Bible teachings is lost – notably that of salvation. An understanding of it is also vital to understanding God himself. Additionally, bear in mind that God’s judgment – being just and righteous – actually gives his people much reason to be encouraged.

But by the same word the present heavens and earth have been reserved for fire, by being kept for the day of judgment and destruction of the ungodly. 2 Peter 3:7 NET

Revelation 11:18 NET
As well as punishment for wrongdoing, God’s judgment includes reward for godliness.
This is evidence of God’s righteous judgment, to make you worthy of the kingdom of God, for which in fact you are suffering. 2 Thessalonians 1:5 NET

One reason why God’s judgment is just is that he judges people with knowledge of all their deeds – as well as of all their thoughts and motives (as per the following subsection). As such he can make judgments with knowledge of all the relevant information.
