2 Chronicles 15:15 ESV
“And all Judah rejoiced over the oath, for they had sworn with all their heart and had sought him with their whole desire, and he was found by them, and the Lord gave them rest all around.”

When King Asa came into power, he cleaned out the idols in Israel and the people made a vow to serve only the Lord. They sought the Lord with their whole heart. Then, God “was found by them,  and the Lord gave them rest all around.”

If we will seek God with our whole heart and serve only Him, and not the things in this life that seems to occupy our time, he will give us rest on every side as He did Israel.
