You really should sing more. You should sing more than at gathered worship with the church. You should sing in the car, while working in the yard, and in your home. And when you sing, you should do so with more than lungs and lips. You should sing with your heart, mind, and soul.
…People sing about the things that capture their hearts and things that give them joy. People sing of heroes, victory, longing, and hope. People even sing as a way to express their sorrow. Does anyone have more reasons to sing than you? As a sinner who has been forgiven, a slave who has been freed, a blind man who has received sight, a spiritual cripple who has been healed – all by the gospel – you have real reasons to be known as a person of song!
It is one thing to tell the world of God’s work of redemption in Jesus; it is another to sing of it. Anyone can parrot truth, but to sing of it – from the soul – reveals how you feel. Song is the natural and appropriate response to the gospel, because singing is one of the highest expressions of joy.
So why aren’t you singing ‘always, only for [your] king?’ Have the mercies of God grown small in your heart? Is there little joy, little gratitude, little wonder? Do you just not feel like singing? The confession of sin and gospel meditation will lead you to song, so start there. There are songs of praise, thanksgiving, confession, lament, and victory that need your voice.
…So join the chorus of God’s people, who have always been known as a people who sing.
