Titus 1: 15 Everything is pure to those whose hearts are pure. But nothing is pure to those who are corrupt and unbelieving, because their minds and consciences are corrupted. 16 Such people claim they know God, but they deny him by the way they live. They are detestable and disobedient, worthless for doing anything good.

what do you think of this scripture?

everything is pure to those whose hearts are pure... well the problem with that is the reality that as much as we pray for it and hope for it and even strive towards it.. our hearts are not pure... 

seems to me I can keep my motives and heart pure for a short while then before long I am back to feeling like doing what God wants me to do is too high a cost... I am not good enough to remain this righteous all the days of my life... 

such people claim they know God but deny Him by the way they live... 

I would have to say that sometimes I fall into that category... sometimes I am just caught up in my own emotions and don't do right... 

I think that learning to control our emotions could be the most valuable lesson we might ever learn.. I personally think it is much easier just to not have any emotions... but if we have to have them.. then surely the key to happiness is in learning to control them and not be led by them...
