"The LORD is gracious and compassionate, slow to anger and rich in love." (Psalm 145:8)
Psalm 145, the last acrostic in the Psalter and the last psalm explicitly attributed to David, is a comprehensive hymn of praise that covers every dimension of God's greatness and goodness. The psalmist commits to a lifetime of praise: every day I will praise you; I will extol your name for ever and ever. Generation after generation will commend your works to one another. The passing on of praise across generations is itself an act of worship: when we tell what God has done to those who come after us, we extend the circle of glory.
The theological centrepiece quotes the divine self-revelation at Sinai: The LORD is gracious and compassionate, slow to anger and rich in love. The LORD is good to all; he has compassion on all he has made. This is the character of the God revealed in the covenant, and it is the character that the whole Psalter has been exploring from every angle. Gracious, compassionate, slow to anger, rich in love: these four qualities are the grammar of divine action from Genesis to Revelation. The Catechism presents them as the attributes that shape the whole moral theology of the Christian life: those who know the compassionate God are called to embody his compassion (CCC 2842).
Brothers and sisters, every day I will praise you. Not when I feel like it. Every day. Make praise a daily discipline the way exercise is a daily discipline: not because every session feels inspiring, but because the cumulative effect is life. The LORD is gracious and compassionate. That does not change. Your praise of it deepens your experience of it.
Lord God, I will exalt you, my King, and praise your name for ever and ever. You are gracious and compassionate, slow to anger and rich in love. Your kingdom is an everlasting kingdom and your dominion endures through all generations. My mouth speaks your praise, and every creature blesses your holy name for ever and ever. Through Christ our Lord. Amen.
