James 2:14 Dear brothers and sisters, what's the use of saying you have faith if you don't prove it by your actions? That kind of faith can't save anyone.
Faith that is not backed up by action is no faith at all. It does no good to believe something to be true and never put it to the test. Anyone can believe in God and what He has revealed about himself. Anyone can claim to know God. But, unless it shows in the way he lives, it's just talk.
Only God knows the sincerity of the heart, but we can get a pretty good idea from how a person lives as to whether or not his talk is really what is true in his heart. Actions are a reflection of the heart. If how you live and talk don't line up with godliness, then you are not saved.
Jesus changes us from the inside out. He changes how we see things, what we think about, and how we live in relationship to others. He never enters into the heart of someone without changing him. The change varies in speed with the individual, but indeed change happens. In place of sinfulness, Christ makes us holy and righteous. It is who He is and He cannot be anywhere where He does not affect the person in whom He resides.
If your living does not match up to your profession, you need to fall on your knees before God today and get things right with Him.
