to yield (something) to the possession or power of another; deliver up possession of on demand or under duress....
I don't know why most Christian songs sing about how sweet it is. It's not sweet at all. In fact, it sucks. You are giving up something under duress or at least not giving it up of your own volition.
Think about generals surrendering in war. Did they really want to do it? No, but they had to because it was between either that and death.
It's a struggle.
It's not fun.
It's not sweet.
It's not great.
But it is needed at times.... When it's either that or death.
