This is a very classic Christian hymn called amazing grace:

5 1—— 32 1 3—— 2 1—— 6 5……

How sweet the strange grace code is ...

The complete lyrics are as follows:

1, amazing grace, how sweet, my sin has been forgiven;

I was lost before, but now I have found it. I am blind now.

2. This kind of grace makes me awe and comfort;

How precious it is to be blessed when you first write!

3. I have survived many dangers, trials and traps;

Thanks to the Lord, I was not afraid at all and took me home.

4. In the coming jubilee, the saints will get together and enjoy the Millennium friendship;

Joy and praise, in front of the father's seat, I hope that day will come soon.

John Newton, the author of this poem, was dissolute and evil in his early years, repented and believed in the Lord in his middle age, and then enthusiastically preached the gospel and did good deeds and tried his best to oppose the slave trade.
