I'm reading through James right now, so you'll notice most of the verses are from there.
"So you see, it isn't enough just to have faith. Faith that doesn't show itself by good deeds in not faith at all -- it is dead and useless." James 2:17
Claiming to have faith is more than just saying you believe in God. When we experience true faith, we are transformed. We can't help but be, act, and look different. Once we are saved, our actions should confirm our faith and commitment to Christ. James uses Abraham as an example. His faith in Christ gave him the willingness to sacrifice his own son, and he was rewarded for it. I wonder if I have that kind of faith. I don't want to simply say I believe. I want my life to reflect that.
