A selection of verses showing that God is and will be our judge.
God's judgements are always just and right:
7 But the LORD reigns forever.
He has prepared his throne for judgement.
8 He will judge the world in righteousness.
He will administer judgement to the peoples in uprightness.
4 Oh let the nations be glad and sing for joy,
for you will judge the peoples with equity,
and govern the nations on earth.
God has now given Jesus Christ the authority to judge:
26 For as the Father has life in himself, even so he gave to the Son also to have life in himself. 27 He also gave him authority to execute judgement, because he is a son of man.
30 The times of ignorance therefore God overlooked. But now he commands that all people everywhere should repent, 31 because he has appointed a day in which he will judge the world in righteousness by the man whom he has ordained; of which he has given assurance to all men, in that he has raised him from the dead.”
Jesus will judge his followers when he returns to the earth:
42 He commanded us to preach to the people and to testify that this is he who is appointed by God as the Judge of the living and the dead.
10 For we must all be revealed before the judgement seat of Christ that each one may receive the things in the body according to what he has done, whether good or bad.
