Never wait to praise God, when things are just peachy.
Praise Him ever - at sun up, at dusk. Praise Him because He is your own personal God.
Can you praise Him when you are in circumstantial pain?
If so, you are numbered among those who know Him well enough that knowing God is Joy in itself, un-affected by anything ... anything.
If not, your joy is circumstantial, fickle, unpredictable, shifting sand... idolatrous! It is more about you than God.
If not, get there - you can, you know! Repent. Be with Him, think on Him. Imagine Him and His enormous love and care for you.
And the things of earth will grow strangely dim in the light of His glory and grace.
Praising is really natural. Complaining is not.
Think on God! Do it a lot, for a long time.
Wrestle against distraction. We've been taught not to listen and think.
Let's recover our natural bent to think long on God.
Eternal and natural therapy for the soul!
You and I were made for this.
