I take this song as someone talking to God, asking him why he waited till now (that's hes dead lying on the floor on the corner of 1st and Amistad) to find him. All he needed was a sign and God never gave him one. Btw Amistad was a slave ship that later became a symbol in the movement to abolish slavery. So basically he was on the corner of Freedom/No Freedom? And 1st when he died. That's just my understanding of the song though.
