I know one day a change will have to come

I heard an old man say this change will come one day
I heard an old man say this change must come one day
I know one day a change will have to come
I know one day a change will have to come

The words of the prophets prevailet
I and I won't suffer today
Evil doer's fade away

I heard a youth man say this change must come one day
I heard a youth man say this change must come one day
I heard a little child say, mama, will this change come my way?
I heard a little youth say, papa, will this change come today?
I know one day a change will have to come

Words of the prophet prevailet
I and I won't suffer today
Evil doer's fade away

I know one day a change will have to come
