1 Christian hearts in love united:
search to know God's holy will.
Let his love, in us ignited,
more and more our spirits fill.
Christ the head, and we his members—
we reflect the light he is.
Christ the master, we disciples–
he is ours, and we are his.
2 Grant, Lord, that with your direction,
"Love each other" we comply.
Help us live in true affection,
your love to exemplify.
Let our mutual love be glowing
brightly so that all may view
that we, as on one stem growing,
living branches are in you.
3 Come, then, living church of Jesus,
covenant with him anew.
Unto him who conquered for us
may we pledge our service true.
May our lives reflect the brightness
of God's love in Jesus shown.
To the world we then bear witness:
we belong to God alone.
This distinguished text about the church's "communion of saints" proclaims that Christians live in union with Christ (st. 1), love each other (st. 2), and serve and witness in the world (st. 3).

It is vitally important that worshipers understand the role of God’s law among us. God gives his law to us, not so that we can earn his favor by full obedience, for even those converted to God cannot obey this law perfectly. Heidelberg Catechism, Lord’s Day 44, Question and Answer 114 says, “In this life even the holiest have only a small beginning of this obedience.” Instead, says Heidelberg Catechism, Lord’s Day 2, Question and Answer 3, through this law “we come to know [our] misery.”
Yet in their new life of gratitude, God’s children “with all seriousness of purpose, do begin to live according to all, not only some, of God’s commandments” (Heidelberg Catechism, Lord’s Day 44, Question and Answer 114). They measure their good works of gratitude as “those which are done out of true faith, conform to God’s law, and are done for God’s glory” (Heidelberg Catechism, Lord’s Day 33, Question and Answer 91).
In other words, though Christ has fulfilled the law for us, “The truth and substance of these things remain for us in Jesus Christ…[and] we continue to use the witnesses drawn from the law and prophets to confirm us in the gospel and to regulate our lives with full integrity for the glory of God according to the will of God” (Belgic Confession, Article 25). Therefore, the Ten Commandments with explanation are included in the third section, “gratitude,” (Lord’s Days 34-44) of Heidelberg Catechism.
