Verses 1-23
Psalm 50 True worship
In a scene that displays his awesome majesty, God commands the whole world to stand before his judgment throne (1-3). He is the righteous judge of all the peoples of the world, and his first call to judgment concerns his own people, Israel (4-6).
God's complaint against the Israelites is not that they have failed to offer sacrifices and offerings. Indeed, they have offered them continually (7-8). But God will not accept their offerings. Instead of offering their sacrifices in a spirit of humble worship, the people were offering them as if they were doing God a favour for which he should be thankful. They offered their sacrifices as if they were giving God something he needed. But God needs nothing; he already owns everything (9-11). The meat and blood of the sacrifices are of no material use to him. God is not like the mortal beings of earth who have to eat and drink to keep alive (12-13). The offerings that he accepts are those based on thanksgiving, obedience and complete trust (14-15).
Turning to judge those who are not his people, God condemns them for their disobedience, lies, adultery and slander (16-20). Because God does not act in immediate judgment against them, they think he approves of their behaviour. They are about to find out that such thinking is mistaken (21). They are warned of God's terrible judgment and invited to accept his free salvation (22-23).
