John Newton on Acts 3:19-21

Alas! I knew not what I did,

But now my tears are vain;

Where shall my trembling soul be hid?

For I my Lord have slain.

A second look He gave, which said:

"I freely all forgive;

This blood is for thy ransom shed;

I die, that thou mayest live

Thus, while His death my sin displays

In all its blackest hue;

Such is the mystery of grace,

It seals my pardon too.

With pleasing grief and mourning joy

My spirit now is filled,

That I should such a life destroy,

Yet live through Him I killed.
