Rejoicing, thanksgiving, testifying, and expressing praise to God is a spiritual discipline. It's a decision that takes practice, and deeply affects us. Choosing to praise, to name the ways God has been good to us, and expressing gratitude, even in the darkest valleys and most difficult days, lifting our voices in song as we express praise to God lifts our spirits and changes the posture of our hearts. In this way, joy is not merely circumstantial or a feeling. It is the fruit of the Spirit that is born when, through praise, we abide in Christ.
