When we accept Jesus as our personal Savior, we are born anew. The Holy Spirit comes to dwell within us and we begin to grow closer to Him and become more like Him. There are times though that we revert back to our old ways. Our old speech patterns come back. Old habits such as worry and defeatism return. We forget that those around us who do not know Him are watching us to see how we rely on Him to help us through troubled times. In so doing, we lose the sweet aroma and emit a sour smell of hopelessness. An unsaved person that witnesses this may conclude that since we say we are Christians yet do not have confidence in Jesus, that there is no reason for them to either. If we turn to Him, praise Him and openly trust Him, then we present the opposite. The fragrance will be one that draws others in and creates a desire to know more about our Lord. It is one that will speak life and joy.
We have an enemy whose main purpose is to snatch us away from Jesus. He doesn't want us to reach others with the Truth. He hates anything that points the way to the Almighty. So he is quite pleased when we fall back into our old ways. He revels at the stench of death. Let's not give him that satisfaction. We belong to Christ. That needs to be our identity, our purpose and our very breath.
