When I taught verse 4 last year, these are the pictures I used (all from the primary manual pictures, except the last one, from the Gospel Art kit):

 

I am a child of God: 2-70 (picture of lots of different kids faces)

His promises are sure: 1-11 (child being baptized)

Celestial glory can be mine: 5-28 (Christ descending form heaven with angels)

If I can but endure: 4-12 (from the GAK--gospel art kit)--picture of the people holding on to the iron rod walking to the tree of life
