31 Days of Purity: The Joy of the Lord

Through the month of March, I am inviting you to 31 Days of Purity—thirty-one days of thinking about and praying for sexual purity. Each day features a short passage of Scripture, a reflection on that passage, and a brief prayer. Day eleven comes courtesy of a guest writer: David Murray.

This day is holy to our Lord. Do not sorrow, for the joy of the Lord is your strength. (Nehemiah 8:9).

Holiness and happiness are inseparable. You can’t have one without the other. Holiness produces true happiness, and true happiness strengthens holiness. The proof?

In Nehemiah 8, God’s people had rightly mourned over their sins. But there came a point when their weeping went on too long and too deep, and God said through Nehemiah, “This is a holy day. Therefore let it be a happy day.” The logic is inescapable. Happiness is not only compatible with holiness, it is an essential part of it. Without happiness, holiness is incomplete. Indeed, it is no longer holiness.

But what kind of happiness are we talking about? Nehemiah defines it as “the joy of the Lord.” It is a joy that comes from God and is centered in God. God gives it and God is it.

And as if we needed another reason to pursue, accept, and enjoy the happiness of holiness, Nehemiah adds the motive: “For the joy of the Lord is your strength!” Holy joy, Christ-centered joy, strengthens us. It produces defensive and offensive strength. It powerfully protects us from evil and it empowers us to fight for good. Holiness, happiness, and hardiness. A blessed trinity from the Blessed Trinity!

Ever blessed God, You are so holy and so happy. Help me to believe that my greatest happiness is found in holiness, and that happiness, true Christ-centered happiness, is my greatest help to holiness. Increase my joy in Jesus that I may increase my strength to resist sin and fight for purity. Amen.


What Now? Consider joining our 31 Days of Purity Facebook group. It is optional, but you will find it a good place to go for discussion and encouragement. (Note: that Facebook group is for men only; here is one for Women Supporting Men).

Today’s devotional comes from David Murray, a pastor, professor, author, and dear friend. He blogs at HeadHeartHand.
