This psalm begins with unquestioning trust at the opening. Then, in the middle of the psalm, comments are made about the opposition and how worthless it is compared to waiting upon God. At the end of the psalm is a teaching with an important point.
v.1-4. The Only Salvation: “From Him cometh my salvation.” He waits only for God, his salvation, rock, and defense.
v.5-8. The Only Hope: “My expectation is from Him.” He waits only on God and trusts only in God.
v.9-12. The Only Strength: “Power belongeth unto God.” Other people trust in riches. Some trust in oppressing others to get ahead, and others rob people to gain wealth. Only God has the strength and mercy he needs for life and service.
