Jonathan Ainger at Ponder Anew lists “20 Hymns Your Kids Should Know.” He also has some good advice about teaching your children to sing hymns.
I grieve for this and subsequent generations of churched children growing up without any awareness of the rich inheritance of hymns, without ever, many not even once, having the opportunity to sing hymns in a congregation, and without internalizing songs of faith that will stick with them and serve them well throughout their faith journey.
For what it’s worth, his list is great.
