Sanctification - what is it?

A gradual growth in holiness?

A distinct and separate work of grace after salvation?

Something only God can have?

The ability to live a sinless life?

I’m not really sure exactly what sanctification is, but I do know that it is not the ability to live a sinless life. The bible says that the Righteous man falls seven times and the Lord sustains him.” That would imply that it’s impossible to lead a sinless life. I’m going to have to study this topic for a more solid answer.
