Hymn Lyrics Search - Name That Hymn

all i need is help w the 1st v if anyone can help me complete ?
some times I must be ????
sometimes a throne on his brow
why he should love me I can't understand
but he's even blessing me now

sometimes I must be a nail in his hand

Sometimes I can see the nails in his hand
Sometimes the thorns on his brow
why he should love me I can't understand
well he's even blessing me now
