"You can't bad-attitude someone into a good attitude."

"It is the kindness of God that leads us to repentance. Notice that it is God’s attitude, His disposition, which motivates us to change. God motivates us with kindness."

From this post.

Or do you show contempt for the riches of his kindness, forbearance and patience, not realizing that God’s kindness is intended to lead you to repentance? 

Romans 2:4
