James 2:14-26 speaks of "faith without deeds is dead", I've heard a lot about that.
I am of the mind that you don't "work" yourself into heaven, or even God's good graces. Nothing you do, or don't do will make Him love you any more, or any less.
So a way that I've thought about it is like this:
Faith = the heart
deeds = the pulse
The pulse doesn't "make" you alive, but it is an indicator. The heart can not beat without there being a pulse. There can be no pulse if the heart is not at work.
But ultimately God makes the heart beat - and we don't "force" the pulse to happen, it is a result to the life that God gave us.
What do you think?
