Psalm 72 was written for Solomon, probably when he became king. But looking beyond this psalm, we will see someone who is greater than Solomon—Jesus Christ (vv.1-3,7). Jesus is to our righteousness of God. The psalmist wants Solomon to be a righteous man, to have a kind of integrity and honesty that it takes to exercise kingly judgement. Jesus Christ has never made a mistake. He is our righteousness, and He does what is righteous.
Next, the writer talks about peace (vv.3,7). We can have righteousness without peace. But we can’t have peace without righteousness. We must first have righteousness with God before we can have peace with Him.
Jesus is the King of righteousness and peace. He also brings a refreshment (v.6). We have a days when our hearts are dry like a desert. But the Lord showers blessing is upon us and produces fruitfulness in us, and all of this leads to victory (v.11). We worship and obey Him who is infinitely greater than the Solomon.
One-day Christ will establish His kingdom on the earth. Through His righteousness rule He will bring peace. He establishes His Kingdom in the hearts and lives of believers. Because of His righteousness, you may have the peace of God in your heart.
