What does the Bible say about promotion and humility?

Psalm 75 emphasizes that all promotion and judgment belong to God. In verses 6-7, it states that promotion neither comes from the east, west, nor the south, but God is the judge who puts down one and lifts up another. This reflects the broader biblical principle observed in the lives of the proud and the humble throughout scripture. For instance, Jesus taught that whoever exalts themselves will be humbled, while those who humble themselves will be exalted. This principle is a key theme in understanding our reliance on God's grace for both our humility and our eventual promotion to glory in Christ.
