This is an activity I sometimes do in my personal devotional time. Try taking a well-beloved hymn and find Scriptural backing for the truths taught in the lyrics. For me, it makes the hymn more precious and meaningful as I sing it. Here is one well-known hymn that I did recently.
Loved with everlasting love[1], led by grace that love to know;[2]
Gracious Spirit from above, Thou hast taught me it is so![3]
O this full and perfect peace![4] O this transport all divine![5]
In a love which cannot cease, I am His, and He is mine.[6]
In a love which cannot cease, I am His, and He is mine.[7]
Heav’n above is softer blue[8], Earth around is sweeter green![9]
Something lives in every hue Christless eyes have never seen;[10]
Birds with gladder songs o’erflow, flowers with deeper beauties shine, [11]
