"I'll not turn back"

I've been greatly blessed as I watched  a youtube - two Korean girls played a beautiful duet. I posted this in Facebook to share with others.

If crosses come, if it should cost me dearly,
To be the servant of my Servant Lord,
If darkness falls around the path of duty.
And men despise the Saviour I've adored.
 
I'll not turn back, whatever it may cost,
I'm called to live, to love and save the lost,
I'll not turn back, whatever it may cost,.
I'm called to live, to love and save the lost.

If doors should close then other doors will open,
The word of God can never be contained.
His love cannot be finally frustrated,
By narrow minds or prison bars restrained.

If tears should fall, if I am called to suffer,
If all I love men should deface, defame,
I'll not deny the One that I have followed,
Nor be ashamed to bear my Master's name.
