If I listed all the bad habits I had before conversion I would face a lifetime ban. Suffice to say that when converted they all fell away. My alcoholism ceased immediately. I'd been self medicating for manic depression for 4 years and the moment I was saved I was delivered. I was simply filled with joy and I couldn't stop smiling. People in the "church" I visited were asking the pastor why I was so happy and he didn't seem to have an answer.
Instead he preached a sermon on why walking around with a "stupid grin" on your face didn't mean you'd been saved. I sat there with the biggest stupid grin on my face...That pastor was a stranger to "the peace that surpasses all understanding"(Phil 4:7) and which manifests as joy for those to whom peace is something completely new.
If you have been converted then this will be a reminder of the joy of Yah Veh, or not as the case may be.
