Psalm 1 presents things very simply. There are two ways to live. One results in blessing, the other in destruction. These two ways are set before Israel and the whole world. We can either live the Word-centered life from God or the sin-centered life fro now. As this Psalm indicates at the beginning of the inspired Psalter, this matter is especially important as we go to worship God. That you too would choose the life of the righteous, justified believer, I want to see from this Psalm three aspects of the righteous man.
The two verses contain are punchy, short commands that seem to flow with a kind of hurried earnestness. This is Paul getting in his last words with urgency and brevity. Looking closely, we find Paul’s words sum up the big ideas of 1 Corinthians as a whole. Moreover, the sort of commands that Paul gives to these Christians who lived in a secular, idolatrous city like Corinth transfer very easily over to our own lives as believers today. The commands sum up they can remain faithful to Christ in the future. The message is simple: Christians must remain committed to Jesus Christ.
