Psalm 144:15 (KJV) 15 Happy is that people, that is in such a case: yea, happy is that people, whose God is the Lord.
Joy characterizes the life of God’s people. There’s a lot of unhappiness going on around us. There’s a lot of unhappy situations people find themselves in. There’s a lot of people who cause pain and sadness. There’s a lot of ways to respond.
We as God’s people act and react to people and situations in our lives in godly ways. Yes, we experience tough times, but our joy is untouched. It’s our choice whether or not we’ll rejoice; and we choose to rejoice—always, no matter how bleak the circumstances and how nasty our surroundings are.
We can’t control what others do and we don’t want to control people either, but we have full control over our own actions and attitudes. We have a beautiful perspective about life. True, we’re treated unfairly and we suffer for being godly, but even that becomes a joy for us.
Danger makes people worried and scared; we have the Lord Who is our impenetrable shield. Wars and rumors of wars frighten others; but the Lord is our victory; He trains our hands and gives us the skills necessary to live victoriously. The mightiest of our attackers are but a mist before God. He Who hurls lightning bolts from the heavens can scatter our most powerful foes very quickly.
So yes, we live in joy—it’s very reasonable for people like us whose God is the LORD.
