Brother Bien is a missionary to Cambodia and has been serving the Lord over there for over 13 years. However, he was afflicted with severe panic attacks, which led to hospitalisation. This is his testimony.
Romans 7:15-20 King James Version (KJV)
15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
16 If then I do that which I would not, I consent unto the law that it is good.
17 Now then it is no more I that do it, but sin that dwelleth in me.
18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
19 For the good that I would I do not: but the evil which I would not, that I do.
20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
This is why Jesus gave us the power to remit sins. So we can transfer sin out of the flesh and then rebuke the spirits out of the flesh.
